Silicone rubber compositions

摘要

A silicone rubber composition comprising (A) 100 parts by weight of a heat curable organopolysiloxane composition, (B) 0.1-30 parts by weight of unexpanded or expanded organic resin-base microspheres, and (C) 0.5-50 parts by weight of a polyhydric alcohol or derivative thereof cures into a low specific gravity silicone rubber elastomer which experiences a minimal compression set at elevated temperature.
