FKM
FKM (Fluororubber) is made from highly fluorinated hydrocarbons. It exhibits excellent resistance to ozone, aging, fuels, petroleum-based oils, greases, aliphatic and aromatic hydrocarbons, while reaching its limits in polar solvents, formic acid, acetic acid, glycol-based brake fluid, ammonia gas, amines, alkalis, and superheated steam. Because FKM is based on co-, ter-, and tetrapolymers with varying fluorine content, the material can be precisely tailored to specific requirements. The temperature range extends from a minimum of -25 °C to a maximum of +200 °C.
