NEW! Fluoroelastomer Basics Webinar

Fluoroelastomer Basics - DOWNLOAD VIDEOGallagher Fluid Seals recently made our Fluoroelastomer Basics webinar available on the website.

This webinar will discuss:

  • Differences between an elastomer and a fluoroelastomer
  • The important role fluorine plays
  • Types of fluoroelastomers and their features and benefits
  • Material performance comparisons
  • Chemical resistance of fluoroelastomers
  • Temperature ratings of fluoroelastomers
  • Considerations when choosing the right fluoroelastomer for your application

What is an Elastomer?

Fluoroelastomer - Elastomer CrosslinksAn elastomer is made up of long chain polymers which are connected by crosslinks.  Crosslinks are analogous to springs and provide an “elastic” (recovery) nature to the material.  The crosslinks are relatively stable, but can break down under extreme temperatures and pressures.

What is a Fluoroelastomer?

Fluoroelastomer - Chemical MakeupA fluoroelastomer differs from other elastomers in that it has fluorine linked to the polymer backbone.  The following is an FKM (ASTM designation for this type) fluoroelastomer.  The addition of fluorine off of the carbon backbone improves the chemical resistance of the material.  The carbon-fluorine bond is the strongest in organic chemistry, and helps resistance to high temperatures.


We will be posting portions of the webinar on our blog, so keep an eye out!  To download the webinar, simply visit our Resources page, or click on the image at the beginning of the article.
