Fluoroelastomers (a.k.a. FKM, FPM) are fluorine-containing high performance synthetic rubbers which have exceptional resistance to a broad spectrum of oils, gases, fluids and chemicals at elevated temperatures and in severe environments. They were developed simultaneously in the late 1950’s by DuPont now Chemours (Viton™) and 3M™ (Fluorel*™*, now Dyneon*™*). Fluoroelastomers were created to meet harsh aerospace industry requirements as technology evolved in the U.S. to address the need for better chemical resistance, flexibility and temperature resistance from synthetic elastomers. ## General Characteristics of Fluorocarbon Elastomers - Good Mechanical Properties - Excellent Chemical Resistance - Wide Useful Temperature Range -40 to +400 degrees Fahrenheit ( - 40°C to 205°C) - Outstanding Weatherability and Ozone Resistance - Excellent Resistance to Gaseous and Liquid Permeation - Good Abrasion Resistance - Good Radiation Resistance - Self Extinguishing or Non-Burning in Air ![chem-equations1.jpg](https://www.pelseal.com/hs-fs/hubfs/chem-equations1.jpg?width=712&height=361&name=chem-equations1.jpg "chem-equations1.jpg") ![chem-breakdwns](https://www.pelseal.com/hs-fs/hub/371179/file-996978981.jpg "chem-breakdwns") ![polyfluro-equation](https://www.pelseal.com/hs-fs/hub/371179/file-544940976.jpg) ***[![For additional information on products, prices and custom formulating for your specific needs, click here.](https://no-cache.hubspot.com/cta/default/371179/75c2a48a-20d4-4e2a-b98d-a33e2becdba6.png)](https://cta-redirect.hubspot.com/cta/redirect/371179/75c2a48a-20d4-4e2a-b98d-a33e2becdba6)*** ***Viton™ and any associated logo is a trademark or copyright of THE CHEMOURS COMPANY FC, LLC used under license by Pelseal® Technologies, LLC*** **Fluorel*™* *and Dyneon™ are registered trademarks of 3M.*   Search this site Search **Latest News** ![New-icon](https://www.pelseal.com/hs-fs/hubfs/New-icon.png?t=1525971720226&width=40&height=25&name=New-icon.png) Commercial Boiler Corrosion Solved with Pelseal Viton™ Caulk ([read](https://www.pelseal.com/viton-caulk-provides-corrosion-resistance-in-boiler-venting)) Flanges leaking acid?
