More Information
Summary:A thermally curable composition having excellent vibration damping properties, and having a small decrease in strength even if heated at high temperature is provided. The thermally curable composition contains a component (a) comprising (a1) a solid rubber, (a2) an olefinic double bond-containing polymer which is liquid or pasty at 22° C., (a3) a hydrocarbon resin in an amount of 0 to 22% by weight based on the total weight of the composition, and (a4) a liquid polydiene; and a component (b) comprising (b1) sulfur in an amount of 1 to 3% by weight based on the total weight of the composition, and (b2) an organic vulcanizing agent in an amount of 0 to 0.2% by weight based on the total weight of the composition.
