Fluorocarbon Rubber FPM

Fluorocarbon rubber materials consist of various fluorine-containing hydrocarbons. They occur as copolymers, terpolymers and tetrapolymers with fluorine contents varying between 65% – 70%. Several different curing systems are used: amines, bisphenols and peroxides.

The materials are highly stable and possess exceptional resistance to oxidation, weathering, fire, chemical attack and swelling in a very wide range of fluids. Used in critical applications where resistance to various fuels and chemicals at high temperatures is required. Can be used up to 200°C and for shorter periods up to 300°C. Used in O-rings, shaft seals, gaskets, fuel hoses, membranes and cable sheaths. Fluorocarbon rubber is quite expensive, approximately 30-40 times more expensive than Styrene-Butadiene Rubber (SBR). A common brand is VITON® manufactured by DuPont Tm.
