A Plastics Guy in the Glass Industry

One of the most fascinating things about the Engineering Plastics Industry is that these materials are used in every industry, at least every industry I’ve come across so far, and that’s a lot! So when I recently visited a glass manufacturing plant I wasn’t entirely surprised to find they had a need for plastics.

As Old as Humans 
Glass was discovered by stone-age hunters in the form of obsidian long before it was first manufactured in any form. The first manufactured glass that we know of dates to Mesopotamia in the 16th century BC. In this day and age it’s hard to imagine a world without our automated glass manufacturing techniques. All you have to do is look at skyscrapers in any city. The beautiful glass that you see on the outside is engineered and produced to some amazing standards.  The same is true of the safety glass in every automobile on the road.  Without automated lines that take the sand, sodium carbonate, and calcium carbonate (soda ash and lime) through the process, cars would not be the same. Modern glass has improved safety, part life, and given designers a freedom to create a virtually endless array of shapes.

Modern-Day Glass Factories
Where do plastics enter into the modern-day glass factory? Inside glass plants, technology has led to many innovations that keep prices down and the design capabilities endless.  Automation allows glass to be consistently formed, tinted, laminated, and packaged, and all at high speeds compared to earlier methods. In this process the conveyors rather than humans handle the glass from furnace to delivery on the factory floor.  To keep the lines moving, glass is sent across conveyor lines while it is still at extremely high temperatures. This has created some challenges on the manufacturing side to be able to move the glass in a way that is gentle enough that the fresh material is not scratched, marred or broken. This is where Engineering Plastics offer benefits to the glass manufacturer as it can minimize these issues.

Glass Stops
Illustrations---Glass-HandlingOver the years glass plants have made stops, a small piece that acts as a ‘bumper’ of sorts. Glass hits the stop which helps to cushion and redirect hot glass as it moves along conveyor lines. Some plants have used phenolics or other plastics to make glass stops. Although these materials work, customers tell us they need to be replaced often as the high temperature of the glass degrades the plastic stops. DuPont™ Vespel® is a unique family of polyimide materials that many glass manufactures have moved to  because of their ability to withstand the high temperatures and impact of hot glass.  As one of the highest performing materials for high temperature environments, engineers have designed rollers, stops, fingers, and wear strips out of DuPont™ Vespel®.  In addition to performing well under extreme heat DuPont™ Vespel® has been noted for its ability to handle the constant impact of glass without deformation or causing marring, scratching, or breakage of the glass. While this material is not inexpensive, customers continue to specify DuPont™ Vespel® due to benefits that include  –

  • Reduced downtime of lines to replace stops
  • Reduced furnace downtime to cool and reheat while production lines are down
  • Minimize product loss due to scratches or other damage
  • Decrease downtime to clean up after product breakage occurs

In a recent application in an auto glass factory, we replaced a graphite based material used to make glass stops with DuPont™ Vespel® SCP-5050.  The customer reported the service life of the stops improved over 5000%! It’s a great reminder to me as we look at engineering plastics that it’s not all about the initial cost of the material, it’s about the savings and improvements to your manufacturing process that can happen when you choose the right engineering plastic for the job. So, feel free to call up your local plastics professional when you are looking for improvements. We may or may not be the right fit, but if we are, you’ll be glad you made the call.

What is Fracking and How does it Work?

Fracking is a slang term for hydraulic fracturing, a process that maximizes the output of natural gas and oil wells to make them productive.

How does hydraulic fracturing work?

When a well is fractured, an operator pumps a mixture of water, sand and a small amount
of chemicals into an oil or gas formation deep underground and applies pressure. The pressure fractures rock layers, releasing oil or gas reserves. The sand holds the fractures open to continue allowing the oil or gas to flow into the well.

Illustration---Fracking-01

As gas or oil comes to the well head under pressure, it brings with it the fracturing water that was pumped, along with natural brines that are present in the deeper layers of the earth. That “flowback” water is separated from the gas and oil at the surface, contained in steel tanks, and sent to deep injection wells for disposal.

Is hydraulic fracturing new?

No. Gas and oil operators have been using hydraulic fracturing around the country since it’s invention by George Mitchell in the late 1940s. (See article link below)

One popular method for creating fractures is the use of frac ports and sliding sleeves. Open hole packers isolate different sections of the horizontal well. A sliding sleeve is placed between each packer pair and is opened by injecting a ball inside the borehole. Typically, a completion string is placed inside the well. The string includes frac ports and open hole packers spaced to specifications.

Frac balls, typically made from an Engineering Plastic, are critical components in cutting edge downhole tooling used in hydraulic fracturing operations. Typically when creating multiple fractures in a wellbore, a completion string is placed inside the borehole with frac ports and sliding sleeves spaced between each section. In order to actuate each sleeve a properly sized frac ball is pumped along with the fracturing fluid inside the well.

Each ball is smaller than the opening in each of the previous sleeves but larger than the hole in the sleeve it is intended to open. The ball shall seat within the sleeve, closing the hole and exerting pressure to slide open the sleeve, opening the frac ports. Once the ports are open the fracturing fluid is diverted to the open hole space outside of the completion assembly causing the surrounding formation to fracture.

At the completion of each fracturing stage, the next sized ball is injected into the well causing the next sleeve to open and so on until all of the sleeves are open and multiple fractures are created within the well. The main advantages of this process being the speed with which the well can be penetrated hence reducing cost.

Engineering Plastics used in Hydraulic Fracturing

  • PEEK
  • TORLON®
  • G10-G11-FR4
  • DuPont™ Vespel®

The Engineering Plastics listed above are commonly found in seals, bushings, thrust washers, back-up rings, and logging tools. Many have properties that provide longer wear and high temperature resistance than more traditional materials.

As in nearly all industries today,  Engineered Plastics are becoming widely accepted as a solution to  bearing and wear issues. The oil and gas industry is no exception.  Engineered Plastics have been found to alleviate  some headaches in the extreme conditions the oil and gas industry meets when drilling deeper to tap into new resources.

A Look at Semicon West 2013

This month I attended the Semicon West show in San Franciso, California.  Semicon is the largest industry trade show for the Computer Chip market and all who service it.

Against a backdrop of declining Personal Computer sales and a flat year in the equipment that makes the chips for the PC’s, I was eager to see if this was going to be a good show.  I was pleasantly surprised to see that the industry is not so much contracting as it is instead getting ready for the next “big thing” and there were a few I’d like to highlight here.

The “Internet of Things” Emerges at Semicon West This Year

An interesting concept floating around at Semicon West this year was the emerging “Internet of Things”.  Steve Wigley, VP of Marketing at LTX-Credence, presented in a session where he discussed this topic in some detail.  In a nutshell, more and more things are connecting to the internet!  Many of these “things” communicate thru Radio Frequency (RF) and as items become RF enabled they are void of the need for wires to pass the data around. So look for fewer wires and more devices around your home and office!

Drevil_million_dollars

Yes, I’d like one trillion sensors please.

One Trillion Sensors!
The term “Trillion Sensors” was also knocked around throughout Semicon West. The term highlights the number of sensors needed to collect the data that is estimated will be computed in our world soon.
Tech giant companies including the likes of Intel are talking about putting as many as 20 billion connected devices into use in the next 5 years.  The number of chips to handle this would be huge, but the number of sensors generating the data is downright mind-boggling. From the perspective of what I do, I can certainly see that these technologies will in crease the need and use of lightweight materials such as DuPont™ Vespel®, and Quadrant Engineering’s PEEK which are currently staples in chip production equipment.

One good example of this emerging technology is your vehicle. Today your car talks to you and tells you when it’s time for a lube job, oil change, or tire rotation.  The next generation of vehicles will have additional sensors that will determine if things like the alignment of your wheels is correct and, if adjustment is needed, the sensor will handle it directly with the factory. It made me think about how technology is changing the face of customer service as well.

Connecting Us for Better Health Care?

Semicon also featured displays showing how circuits can be printed right onto our skin. These breakthroughs in technology show how circuits on skin can hold a variety of possibilities, from monitoring the bodily functions of patients without the use of so many chords and connections to machines, to immediately reporting changes in a patient that may be helpful in a recovery room setting where seconds can make a big difference in survival.

Driving much of this development will be the new “sensors” (see photo on right) designed to gather data.  Each sensor will run through a processor which will take the information and that, in turn, will drive an action like sounding an alarm at the nurse’s station for example.

Semicon West Speaker Looks at Dollars and Market Value. The Message – Mobile Devices Rule!

I have heard it said that mobile devices are now used more often to access the web than traditional computers and Semicon West offered proof of that this time around. In fact, I think I read it in an article I saw on my iPad. A speaker at Semicon noted a new milestone that occurred the week of the convention when the dollar value of semiconductor revenue from mobile devices surpassed the revenue from traditional PC and Notebook computers. So, I it certainly appears the trend toward smaller and more powerful technology will  continue its evolution in coming years and I expect we will see much more of that at next year’s Semicon West.

If you are looking at your calendar for next year. I say be sure to put Semicon West 2014 on it folks. From what I saw at Semicon 2013, the 2014 show will be the dawn of even more new and amazing technology. Attendees will never be thinking “Oh its the same old thing at Semicon West.” On the plastics front, look for more lightweight materials like Semitron MP370 to become popular in the all important test sockets which ensure chips are as perfect as possible. If you haven’t heard of Semitron MP370 yet, check out the overview on our website by clicking here

I for one am already looking forward to seeing what’s in store for next year at Semicon West 2014. Of course I’ll be on the lookout for how plastics are being utilized in this field and I’m sure there will be a good showing of that I won’t want to miss learning about. Will I see you there?

Typical Properties of Dupont Vespel® and UL Ratings for Plastics

vespelWhen customers ask us about DuPont™ Vespel® the most often asked question is about UL approvals. The properties of Vespel® are ideal for high heat applications. Does DuPont™ Vespel® meet UL ratings for plastics? If so, which DuPont™ Vespel® meets which UL approval?

DSC_1986_composite RodWhat Are the Different UL Approvals for Plastics and What do they Mean?

The UL 94 rating is specifically for plastics flammability. Underwriters Laboratories created this standard to give people a consistent standard to be able to communicate and compare different types of plastics and how they react to flame. The system goes from lowest being the least flame retardant, to the highest being the most flame retardant. The rating also gives information about the exact testing method used such as:

  • Was the material vertical or horizontal
  • How thick
  • Were colors added

All of these can vary how a material such as DuPont™ Vespel® will react when exposed to flame. In the selection of materials for high heat applications, electronics, or areas that have potential for fire, UL ratings and their purpose must be fully understood and considered carefully.

One possible example is the Boeing Dreamliner. Although it will likely take years to determine, the materials used in the Boeing 787 Dreamliner are being carefully looked at with an eye toward the UL ratings and whether or not selected materials were used appropriately with regard to their rating.

  • UL 94-5VA Surface Burn; Burning stops within 60 seconds, test specimens MAY NOT have a burn-through (no hole). This is the highest (most flame retardant) UL94 rating.
  • UL 94-5VB Surface Burn; Burning stop within 60 seconds, test specimens MAY HAVE a burn-through (A hole may be present)
  • UL 94 V-0 Vertical Burn; Burning stops within 10 seconds, NO flaming drips are allowed
  • UL 94 V-1 Vertical Burn; Burning stops within 60 seconds, NO flaming drips are allowed
  • UL 94 V-2 Vertical Burn; Burning stops within 60 seconds, Flaming drips ARE allowed.
  • UL 94 H-B Horizontal Burn; Slow horizontal burn test (H-B) are considered self-extinguishing”. This is the lowest (least flame retardant) UL94 rating.

How long before the material stops burning (It must stop within 10 seconds for approval) Remember that UL ratings do not tell you the operating temperature of a material. UL ratings only refer the the behavior of a material when it if exposed to a flame source. Material sample are held over an open flame from a Bunsen Burner. After being ignited and allowed to burn the material is removed and testers monitor:When considering use of DuPont™ Vespel® and it’s UL rating there are other important factors to consider:

  • If material continues to burn does it drip or run. If it does, the material cannot be UL approved

How Tribology Led to the use of DuPont™ Vespel®

Tribology is based on the Greek word for “rubbing, grinding”, or “wearing away”. It’s study has lead to advances in material selection for high load applications such as bearings. Plastic materials such as DuPont™ Vespel® have been key in reducing friction and adding cost savings in the long run.

Tribology is a highly pervasive occurrence that can cause parts to have a much shorter life. So pervasive that it became a study all it’s own. In 1964, Peter Jost, a lubrication expert was inspired during a conference and out of this he began an entire discipline around tribology. You can learn more about Professor Jost in this interview Today we have many lubricants that range from the natural to the synthetic. They can all help to reduce friction. Thanks to the world of plastics we also have some materials like DuPont™ Vespel® that provide vast improvements beyond lubricants These new polyimide materials allow engineers to create parts and machinery they never thought possible and to greatly improve the efficiency and life of those parts.

We can thank the discipline of tribology for longer part life.

We can thank the discipline of tribology for longer part life.

Just think, if you had asked for a 10 year / 100,000 mile warranty 20 years ago the sales person would have laughed for a very good long time. Now, it’s the standard thanks in part to the discipline of tribology and new materials like Vespel. Due to their properties materials like DuPont™ Vespel® have found their way into commercial transportation industries, medical, food processing and manufacturing of all types. They simply have a unique combination of properties that makes them highly durable even under the harshest conditions.

Plastic materials are making a big difference in our ability to reduce friction and cost due to reduced wear and less need for lubrication and maintenance.

DuPont™ Vespel® has been a marvel of the plastics industry for decades. Now the SCP family of materials has been added to help with extended part life in sealing and bearing applications. It is most noted for it’s ability to be used in non-lubricated high-friction environments because of it’s exceptional heat and pressure resistance capabilities. The SCP 5009 material in particular performs well with or without lubrication under conditions that would cause severe wear or destruction of most other plastics. SCP 5009 is often used in bearing applications because it will reduce or eliminate problems with abrasion, corrosion, adhesion fatigue, and wear that plague conventional options such as metal bearings. Addition of a lubricant can improve performance even more!

Technical Properties of DuPont™ Vespel® SCP 5009

 

Technical Data for DuPont Vespel SCP 5009

Technical Data for DuPont Vespel SCP 5009

(Technical data provided by DuPont)

Using DuPont™ Vespel® SCP-5009 shapes for seals, valves, bearings, bushings, and other components can mean savings due to lower replacement rates which leads to reduced maintenance costs. It’s also easy to machine. Most Vespel can be machined on the same equipment used for metals like brass. (See our video on machining techniques) and that can mean fewer rejects, higher productivity and reliability.

Key industries that have studied tribology and found that DuPont™ Vespel® SCP-5009 shapes can offer substantial processing, performance and metals replacement advantages include analytical instrumentation, medical devices, aerospace and energy and material handling.

In a comparison to metal ball, needle and roller bearings, a part made from high temperature material like DuPont™ Vespel® SCP-5009 has advantages that include:

• No external lubrication
• The ability to hold up in temperature where lubricants fail
• Perform in dirty environments including dusty or where lint is present
• They typically weigh less and are quieter
• Compared to porous metals, bronze and brass the wear life may be much greater
• Vespel holds up to high pressure and high velocity
• Creep resistance

In addition, SCP 5009 can perform at temperatures and velocities beyond that of other plastic materials.

SCP 5009 is just one example but it’s one that shows how, thanks to the discipline of tribology, plastics are becoming more mainstream in manufacturing and it’s not due to a short term gain of cheaper material. Rather tribology has given us a longterm view of parts that looks at longer life, less maintenance and improved performance. Therein lies the true value and savings.

Do I Need to use DuPont™ Vespel®?

It seems like nearly everyday we hear about a new breakthrough advancement in plastics materials. From biodegradable to new engineering plastics and more. Why I just recently posted one on our Facebook about a new invention that is being called OLED (https://www.facebook.com/AINPlastics). These new products and materials have features we couldn’t even imagine 10 years ago. So how do you know when you need to use certain products and when could you maybe use something a little less costly?

In this blog post, I wanted to take a look at one product in particular that we’ve talked about before; DuPont™ Vespel®. There has been a lot written and said about DuPont™ Vespel® and it’s with good reason. It’s been around for a long time (Since the early 1960’s) and the DuPont™ Vespel® product line offers some pretty unique features. But it’s also not the most inexpensive to purchase so we’ve created an easy top 10 list of things to consider when making product selection and considering whether or not Vespel® is right for your application…

The Top 10 Things to Consider when Thinking About Whether or not DuPont™ Vespel® Is the Right Material for Your Application:

1. When you have a critical application such as aerospace or military where DuPont™ Vespel® may be the ASTM specified product. (See our post “When Saving a Little can Cost you a Lot”). If it is specified you can stop reading here. You’ll want to be sure you follow the standard.

2. When you want a plastic material that will hold up in a high temperature environment and not lose it’s properties. DuPont™ Vespel® SP-1 and SCP-5000 can operate in temperatures up to 550° F with excursions up to 900° F! In fact, SP-1doesn’t even have a melting point. Gheesh, I’m melting in our Michigan weather this summer, but as hot as it is here, we aren’t even close to those temps!

3. When you have a high load application such as a bearing.

4. When you are looking for weight savings DuPont™ Vespel® can be an excellent alternative to metals such as aluminum or metallic alloys, or ceramics. It’s properties may even exceed that of metal and ceramic.

5. When you are working in a critical testing environment and need a low outgassing product.

6. When you need a long-lasting material. Low friction and high stability along with heat and wear resistance mean your parts last longer and require less maintenance.

7. Variety. In the “S” product line alone DuPont™ has over 10 products to choose from. This can help to save money as you don’t always have to get all the bells and whistles, but instead get a product that fits your specific application needs.

8. An easy to machine alternative to ceramic. VDuPont™ Vespel® has electrical insulative properties like ceramic, but the ease of machining using standard machining techniques means it can cost less to fabricate Vespel than it does ceramic. This is especially true for design that include details like under cuts, holes, or threads. Vespel is also tougher than ceramic and it can take high impact.

9. When lubrication may not be viable or when you need a low wearing material that can withstand poor tolerances or when you need low friction to improve efficiency. DuPont™ Vespel® Bearing Grade SC and SCP possess some of the highest unlubricated pressure-velocity limits among engineering plastics.

10. When you need a plastic with high chemical resistance, or that will work well under hard vacuum, radiation, oxygen compatibility, cryogenic conditions, and exposure to flame.

Common Uses for DuPont™ Vespel®
Now that we have 10 considerations did you want to know what DuPont™ Vespel® is being used in? OK, we pretty much mentioned aerospace and military. But beyond that you can find Vespel in snowmobiles, ATV’s, farm equipment, and semiconductors. Since 1964 Vespel has been used in transmissions, small motors, brake pad assemblies, seal rings, valve seats, bushings, washers, thrust plugs, anti-lock break systems, fuel systems, turbo chargers, vacuum pumps, door hinge bushings, belt tensioners, gear stick rollers, rubbing blocks,wheel disc nuts, steering and air conditioning systems, suspension systems, intake and exhaust systems, piston rings. Handling of hot glass in manufacturing of bottles and hot runner systems in plastic packaging manufacturing are two more! In other words it’s pretty tried and true in a lot of applications. It may not be right for yours, but to find out see how many of your needs are in the top 10. After that if you need more detail on specific DuPont™ Vespel® products, take a look at the following links. They will take you to product technical data for each DuPont™ Vespel® material. If you don’t have the time to do all that comparing, give us a call and ask one of our people. We can help you determine if Vespel is right for you, and if so, which one fits your application best.

New Video Coming Soon!
Just a heads up…we’ve got a new video coming soon. Above we mentioned Vespel machines easily and in our video we will show just how easily DuPont™ Vespel® machines and we will offer some tips and tricks we’ve learned over the years that can help you get the best out of these materials.

Until Next Time!

Aerospace Utilizing More Plastics



When you talk with Paul it is clear that he truly enjoys his work and shares a passion for flight, with his aerospace colleagues. Paul says, “To me, It’s almost magical to see a Boeing 777 loaded with over 400 people in it’s cabin, thundering down the runway powered by just 2 jet engines.”  The “Boeing Triple 7,” as its now known, was launched in 1990, over 20 years ago.  At that time it was unheard of to fly around the world in a passenger jet with only 2 engines. Thanks to the Triple 7 plane Boeing proved that long flights were indeed safe and with that realization Boeing changed air travel forever.

Paul noted that on the first Boeing 777 plane it was highlighted that 10% of the plane was made of non-traditional composites and yes – PLASTIC!  It was also the first jumbo passenger jet to implement “fly by wire” controls, now considered the norm for newer planes.  As we’ve all heard in the news, rising fuel costs have dramatically affected travel cost whether by air or other means. Since fuel is the largest expense on a commercial flight, weight factors have become precious numbers in the calculations of whether a new plane makes sense for an airline to commit to adding it to their fleet.  The Boeing 777 LR lifts off at nearly 750,000 lbs. and that’s a lot of weight to move around, so any savings in weight can add up over time to a big difference in cost! DuPont™ Vespel’s® SP-1 and SP-21 can be found on many components including the engine area and many of the control systems.

Today Boeing is starting to deliver the first of over 700 orders for their newest aircraft, the B-787 Dreamliner.  This engineering gem will cut operation costs by over 30% compared to a large B-767 jetliner.  It’s no surprise that Composites and plastics will replace even more steel than ever before on a jumbo jet.

AIN Plastics is one of several ThyssenKrupp Material Divisions that have been deeply entrenched in Aerospace for many years.  Steel and aluminum have been major components of aircraft since the Wright Brothers determined that wood and fabric could only go so far in air travel, and with the high tech engineering plastics we now have AIN Plastics expertise has been welcomed into the aerospace business as well. Paul says he is not surprised that these days plastics are finding their way into more parts of today’s jetliners just as they are finding their way into cars, trucks and other vehicles.  In both aerospace and automotive industries the benefits of choosing plastics stem from many of the same reasons:

  1. Lower weight means less fuel used
  2. Specialized Engineering Plastics can eliminate the need for lubrication (like internally lubricated DuPont™ Vespel’s® SP-22 and SCP-5050)
  3. Plastics can extend the life of mating parts because they wear well under extreme conditions such as high heat
  4. Plastics can last longer than steel in corrosive environments
  5. In some cases plastics can rival or surpass the properties of previous materials including metals, wood, and more.

Throughout Paul’s work in the plastics industry he has found when it comes to plastics, no material is more high tech than DuPont™ Vespel®.  He explained this family of Polyimide Thermoplastics can handle temperatures over 550°F  with excursions up to 900°F.  Some Vespel® is graphite filled to reduce friction, others have a coefficient of thermal expansion close to that of steel. The unique combination of benefits is what makes Vespel® the choice material for Actuators, Bearings, Bobbins, Bushings and many other components that work behind the scenes to keep the mechanical functions of an airplane functioning. In fact, DuPont™ Vespel’s® use in aircraft is mandated by ASTM Standards (ASTM D 6456-99, MIL-R-46198) as the material to be used in numerous applications. For more on this, see our earlier blog post titled “When Saving a Little can Cost you a Lot!” Paul noted too that “AIN Plastics is the DuPont™ Vespel® Authorized distributor so you can always buy with confidence that you are getting authentic DuPont™ Vespel®.”

When Saving a Little can Cost you a Lot!

…aka why it’s Important to Choose Authentic DuPont™ Vespel®


In business we are always looking for ways to save money and ways we can take that savings and turn it into making more money and better profits. While there are a lot of good ways to do this, like shopping online and comparing prices to get the best deal, when you add up all the costs, sometimes those dollars aren’t worth the savings.

In fact, at times there can be serious consequences. This is actually from a blog post we initially published some time ago. But it’s so important that we like to be sure the information stays out there.

Authentic DuPont™ Vespel®

Authentic DuPont™ Vespel®

Machine Shops Beware!
Over the years there have been reported instances of DuPont™ Vespel® shapes being machined into smaller diameter counterfeit rod from larger diameter rod by unauthorized resellers.  In these instances, the unauthorized resellers attempt to sell the product as Authentic DuPont™ Vespel® shapes to unsuspecting machine shops.  Instances of altering the original Certificate of Conformance (CoC) to reference the smaller diameter have been discovered as well.  These altered CoCs do not contain the correct lot number information intended to match product size and composition for traceability purposes.

Why Is This Important?
Unlike Authentic DuPont™ Vespel®, these counterfeit altered rods do not meet ASTM D 6456-99, MIL-R-46198 and OEM Specifications.  In fact, the characteristics of these counterfeit rods differ from rod made to the original size in the proprietary DuPont™ isostatic molding process.

It is important to note that when your customer qualifies a material they are not only specifying the grade of resin. They are also qualifying the process in which the material is formed. When  it comes to DuPont™ Vespel® testing has shown that smaller diameter rods ground down out of a larger rod are not the same. SP-1 data indicates that smaller diameter ISO rods have a statistically higher tensile strength and elongation than larger diameter rods. Similarly, testing on rods ground out of DuPont™ Vespel® Plaque show differences from ISO rods.
So, in the long run, shopping around and finding that great deal on something that says it’s DuPont™ Vespel® could cost you far more than the dollars you saved by going with something that appears to be close enough to do the job.

But if it’s Made from DuPont® Vespel® Material What’s the Problem?
To answer that, let’s take a look at ASTM Standards and the organization that creates the standards – The International ASTM organization was founded in 1898 and with more than 30,000 members it is one of the largest voluntary standards developing organizations in the world. They strive to maintain a no border policy meaning the organization is made up from people all over the world (over 100 countries) and all walks of life from industry, to government, to just regular people in the private sector.

What Exactly Is an ASTM Standard?
According to the ASTM website: “As used in ASTM, a standard is a document that has been developed and established within the consensus principles of the organization and which meets the requirements of ASTM procedures and regulations. Full consensus standards are developed with the participation of all parties who have a stake in the standards’ development and/or use.”

Voluntary Organization? If  it’s Voluntary What’s the big Deal?
Although the standards are voluntary many governments, including the U.S. cite ASTM standards in laws giving them much greater power. In 1995 the U.S. passed the National Technology Transfer and Advancement Act (Public Law 104-113). This law requires government agencies to use privately developed standards instead of investing taxpayer dollars to create their own. The law saves tax payers a huge amount of money and it also means more ASTM standards have become part of U.S. laws. To read the Law in it’s entirety click on this link: Public Law 104-113 pdf

What Does This Mean for Machine Shops and DuPont™ Vespel®?
ASTM Standards are used in numerous industries including aerospace, automotive, petroleum, even sports and recreational equipment. Large manufacturers use ASTM standards to guarantee product quality. ASTM standards hit us in our daily lives too. Sports organizations are making certain participants in their events use protective gear that meets an ASTM standard. In the aerospace industry the ASTM Standard states that only DuPont™ Vespel® may be used. So, any altered product such as ground rods, or any similar product does not meet their standard and therefore using it in what you do for an aerospace company means you are going against the rules they have set in place to ensure the highest quality products are used when building aircraft. Supplying them with a product that is anything less than their standard sets you up for being liable should anything happen. We all know what that means – potential law suits and possibly even worse.

Still Worth the Money Saved to get a product that almost meets the standard?
If not, how do you know you’ve got the real deal? Contact AIN Plastics, Division of ThyssenKrupp Materials NA. As the authorized distributor, AIN Plastics will provide you with the lowest possible price for authentic Dupont™ Vespel® shapes such as rods and plaques.
