RUBBER COMPOSITION FOR POWER STREEING

摘要

PURPOSE: A rubber composition for power steering is provided to improve tensile strength and durability, to prevent damage from high pressure generated from power steering and to suppress the performance degradation of the power steering. CONSTITUTION: A rubber composition for power steering comprises 100.0 parts by weight of polymer, filler consisting of 45-70 parts by weight of carbon black and 7-30 parts by weight of graphite, 5-10 parts by weight of cross-linking agent, and 1-10 parts by weight of plasticizer. The cross-linking agent comprises dicumyl peroxide. The plasticizer comprises ether-ester.
