VITON

Viton® rubber is a high specification fluoroelastomer that is suitable for demanding environments where elevated temperatures and chemicals are present. Viton® is able to retain its physical and mechanical properties, such as flexibility and fluid resistance, in situations where lesser specification elastomers begin to swell and break down. It displays excellent resistance to acids, oils and petroleum based products, making it a popular gasket and seal choice in the automotive, aerospace, oil and gas, and chemical processing industries.

Viton® can be supplied in two grades as standard: Type A and Type B. Both types have similar properties and resistances, but the increased fluorine content of type B (68.5% compared to type A's 66%) provides better fluid resistance, increased flexibility after heat ageing, and better sulfur dioxide resistance. As such, it is more frequently used in chemical processing and power generation applications.

- Shore Hardness: 75° ± 5° (type A), 70° ± 5° (type B)
- Temperature: -20°C up to +275°C (type A), -30°C up to +300°C (type B)
- Outstanding resistance to acid, oil and petroleum based fluids
- Excellent ozone resistance
- Low permeability
