Why Thermoplastic Elastomer?

Thermoplastic works for most seal applications without the blooming, staining, bleeding, and smelling that you get with rubber, it’s recyclable, and it even weighs less. If your still thinking rubber when it comes to seals, now’s the time to re-consider and we are here to help.

In this guide, we answer questions like:

  • How is TPE different from rubber?
  • Why would I want to switch to TPE in my application?
  • Will TPE even work for my seal?
  • What TPE compounds do I have to choose from?
  • What are the nuances and practicalities of retrofitting my current design to a TPE?

… And more

We know how difficult it can be to champion change. That’s why we created this guide. It provides the basic guidelines for converting rubber seals and weather stripping to TPE – all from the perspective of an experienced seal engineer. This is not an exhaustive guide; the amount of information available is simply too great. However, it serves as a starting point to better understand TPE’s and what you should consider when designing with them.

We’ve spent decades developing over 7,000 extrusion profiles and manufacturing millions of dual- and tri- durometer seals. You can be confident that we have the resources and expertise to help with your unique application.
