Viton® Sheet Rubber
Viton® was originally introduced 50 years ago to meet the needs of the aerospace industry for a high-performance elastomer. Since then, the use of Viton® 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.
Particularly valued for its excellent heat stability (200°C) and resistance to aggressive fuels and chemicals, Viton® is the most specified fluoroelastomer for fuel system seals, expansion joints and gaskets.
