COMPOSITION FOR RUBBER VIBRATION INSULATOR, AND CROSSLINKED OBJECT OBTAINED THEREFROM

摘要

The present invention addresses the problem of providing: a composition that includes an epichlorohydrin-based polymer for imparting satisfactory vibration-damping properties while maintaining tensile strength and heat resistance, which are expected of rubber materials; and a crosslinked rubber material obtained by crosslinking the composition. The present invention relates to: a composition for rubber vibration insulators, characterized by comprising an epichlorohydrin-based polymer, silica having a CTAB-adsportion specific surface area of 50-150 m2/g, a silane coupling agent, and a crosslinking agent; and a material for rubber vibration insulators which is obtained by crosslinking the composition for rubber vibration insulators.
