Viton® & Fluoroelastomer Sheet Rubber

All of our Viton® and Fluoroelastomer products are manufactured with 100% virgin FKM Fluoroelastomer.

Fluoroelastomers were originally introduced over 50 years ago to meet the needs of the aerospace industry for a high-performance elastomer. Since then, the use of Fluoroelastomers has spread quickly to many other industries, including the automotive, fluid power, appliance and chemical industries and has developed a reputation for its outstanding performance in very hot and extremely corrosive environments.

Fluoroelastomers are particularly valued for their excellent heat stability (200°C) and resistance to aggressive fuels and chemicals.
