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.
