Your Guide to Plastics Past, Present, and Future…

Lisa Anderson, Marketing Manager ThyssenKrupp Materials NA, AIN Plastics Division

It’s hard to believe it’s been over 6 months since I began working at AIN Plastics. Hard to believe because everyday is packed full of lots of projects and lots of things to learn about plastics. There have been new people to meet and old friends to reconnect with, and it’s all been really fun, so the time has truly flown by.

As I’ve gone through these months I developed a hunch. My guess is, when it come to plastics for manufacturing and specialty uses, a lot of you in many industries are in the same boat because there are so many material choices out there. So I’m inviting you to take the journey along with me to learn about plastics. What are plastics, what are the different types, why are they being used more and more, and what plastics will work for your applications. In fact, I hope you’ll share your applications and experiences as well.

While we are at it we’ll take a stroll through plastics history too. I’m a huge history buff so every time I hear about a plastic I like to dig in and find out how it all started. These days plastics seem to surround us, but it wasn’t that long ago we relied on other materials such as wood, metal, and glass for everything from IV ‘bottles’, to baby bottles, cooking utensils, sporting equipment. Hmmm – what were shower curtains before plastic? I’ll get back to you on that one, or if you know, please share! We love comments.

So let’s get started! Today I’d like to stay in the present and take a look at a helpful piece that came across my desk. As we all know there are literally thousands of types of plastic materials out there and more are hitting the market all the time, so anytime there is something that can help you to select the best one for the job we here at AIN will be sure to share it with you. After all, getting the right material helps everyone. The item that came across my desk is in regards to Materials for seals and gaskets.

So let’s start with a couple of questions –  
• Do you make seals or gaskets?
• Do you need your seals and gaskets to be Teflon®?
• Do you have a high temperature application?
• Do you need FDA compliant seal and gasket material?

The most common choices for seals and gaskets are UHMW – PE, Teflon, and PEEK. These are all great options, but another material called Fluorosint® has, until now been a little less known for seals and gaskets however, it is proving to give material specifiers another excellent option for certain higher temperature applications. Two Fluorosint® materials are FDA compliant giving you options for special applications in food or medical applications.

In selecting material for gaskets and seals temperature and pressure are the two biggest factors people generally consider. This chart easily shows where TIVAR® UHMW-PE, Teflon®, Ketron® PEEK, filled and unfilled PTFE, and Fluorosint® and Duratron® fit in as material options. Test results clearly show that Fluorosint® and Duratron® fit very well into a gap left for high temperature and high pressure applications. To make your selection even more exact, Quadrant (manufacturer of Fluorosint®) has developed several Fluorosint® materials (207, HPV, 500) and each was specifically developed with a certain application area in mind.

Below is a Material Selector Guide that covers all of these materials in two easy formats. One simply compares how a product does in relation to heat and pressure. The other compares Fluorosint® to Rulon®, another common material for seals and gaskets. You can also compare the FDA compliant materials.

From materials suitable for average heat and pressure to the highest, this chart will help you to easily cross reference common seal and gasket materials.

Compare test results of Fluorosint and Rulon and see at a glance what material fits your application.

As we go forward I’ll be looking at each of these products on an individual basis. But, if you see something here you like and you want to know all the details right now, we do have more information available on our website: Fluorosint Product Information. You can also talk to one of people. We have a knowledgeable staff that can help with any questions you may have about seal and gasket materials. Just call 877.246.7700 and you will be connected with the AIN Plastics office nearest you.

If you are along for the journey that’s great!  If seals and gaskets aren’t your thing, no worries, I’ll be talking about all sorts of other materials as we go. In fact, you can sign up and get our posts in your mailbox so you don’t miss the latest.

I hope you find these charts helpful in your search for that just right seal or gasket material. We’ll see you in the blogosphere again very soon!
