[VIDEO] Basic Understanding of Fluoroelastomers

Fluoroelastomer Basics - DOWNLOAD VIDEOGallagher Fluid Seals recently posted our new Fluoroelastomer Basics webinar on gallagherseals.com.  This is the first section of our webinar, focusing on the Basic Understanding of Fluoroelastomers. The full video is now available on our Resources page.

In this snippet, learn the differences between elastomers and fluoroelastomers, and how the amount of fluorine in an elastomer affects it’s chemical resistance and properties.

Chemical CompatibilityA common question fielded by Parker O-ring Application Engineers is “will a (insert polymer family) O-ring work with (insert chemical mixture).” Not a day goes by where I do not field this question in some way, shape, or form. Which, honestly, makes perfect sense, because chemical compatibility is one of the two most important factors in designing a seal, the other being size. Choosing the right compound can literally make or break your seal and to the general designer, this can be a massive undertaking. There are so many rubber compound families out there and hundreds and hundreds of chemicals, so how can you know whether your seal is going to hold up? Well, today, I hope to give you a simple, and quantitative way to figure that out.
