RUBBER COMPOSITION FOR ANTI-VIBRATION RUBBER

摘要

A rubber composition for anti-vibration rubber containing a rubber component wherein the rubber composition for anti-vibration rubber contains 4-40 parts by weight of lithium catalyst-type polyisoprene rubber, taking the weight of the entire rubber component as 100 parts by weight. The composition also preferably contains 30-80 parts by weight of Ziegler catalyst-type polyisoprene rubber and 10-30 parts by weight of polybutadiene rubber. The composition also preferably contains less than 0.6 parts by weight of sulfur-based vulcanizing agent per 100 parts by weight of the rubber component.
