Composition for vibration isolating rubber and anti vibration rubber product

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition that makes it possible to produce a vibration-proof rubber having improved dynamic-to-static moduli and compression set than those of the conventional EPDM vibration-proof rubber.SOLUTION: A vibration-proof rubber composition contains a copolymer of ethylene, C3 to 20 α-olefin, and nonconjugated polyene (A) 100 pts.wt, and hydrophobic silica surface-treated with hexamethyldisilazane (B) 1-100 pts.wt.SELECTED DRAWING: None
