Viton - Rubber

Following its introduction, the usage of Viton^® spread quickly to other industries including the automotive, appliance, chemical and fluid power industries. Viton^® has a strong reputation as a high-performance elastomer in very hot and extremely corrosive environments. Viton^® was also the first fluoroelastomer to obtain worldwide ISO 9000 registration.

Viton^® is a registered trademark of DuPont Performance Elastomers.
