Viton is a brand of FKM, a synthetic rubber and fluoropolymer elastomer . The name is a registered trademark of The Dupont. Viton are elastomers that are commonly used for O-rings. These kind of polymers are compounded for low compression set. This means that they will recover well after a fixed time under specified squeeze at a given temperature. These elastomers are also highly flexible and can be stretched to a great extent, without breaking. Such elastomers are commonly used as gasket material, but are also employed for making rubber valves, rubber pumps, and related components.
Viton properties are very unique:
Temperature – Viton temperature resistance ranges from -20°C to 210°C,
Chemical resistance: Viton is resistant to mineral and vegetable oils, gasoline, most alkalis and aromatic hydrocarbons.
Cost: As an approximate guide, Viton compound is more expensive
