RUBBER COMPOSITION FOR BRAKE BOOSTER

摘要

A rubber composition for a brake booster is provided to improve heat resistance, low temperature property and brake oil resistance, thereby preventing the performance deformation of a brake booster even in case of the increase of internal temperature. A rubber composition for a brake booster comprises 100 parts by weight of an ethylene propylene diene monomer(EPDM) polymer; 2-20 parts by weight of an inorganic filler; and 0.5-20 parts by weight of a co-crosslinking agent. Preferably the inorganic filer is talc; and the co-crosslinking agent comprises trimethylolpropane trimethacrylate.
