FFKM-rubber compounds with excellent resistance to corrosive fluids

FFKM is a family of perfluoroelastomer compounds that contain even higher amounts of fluoride than FKM. FFKM provides an exceptional high temperature(600°F/320C) and chemical resistance, and can even withstand prolonged exposure to oxygen-plasma. Food and medical grades are also offered.

Area of Application

FFKM are used in highly aggressive chemical processing, semiconductor, flat panel industry, petroleum, pharmaceutical and chemical industry.

Area of Application

Chemical Resistance

For strong acid, amines, ethers, organic solvents, etc., with excellent chemical resistance, thereby increasing the stability of the seals in a variety of solvents.

High Temperature Resistance
