Kalrez is a registered trademark of DuPont Performance Elastomers L.L.C.(DPE). These parts are based on perfluoroelastomeric material which is compounded and moulded into O-rings, gaskets, and speciality parts. Kalrez has excellent resistance to temperature and chemicals, some grades have a maximum continuous service temperature of 327°C. Perfluoroelastomer (FFKM) O-rings and gaskets are generally used in applications of aromatic hydrocarbons and in highly corrosive fluids and can generally withstand to a temperature of -7 degree Celsius to maximum of 480 degree Celsius, at which point the material decomposes.
