Abstract
A silicone rubber sponge composition obtained by compounding a polyorganosiloxane having an average degree of polymerization of 3,000 to 300,000, a reinforcing silica filler, 1,1'-azo-bis(1-acetoxy-1-phenylethane) as a foaming agent, and organic peroxides and/or addition reaction curing agents. The silicone rubber sponge composition can provide a silicone rubber sponge which has a high foaming ratio, has a fine and uniform cell structure, has excellent surface smoothness of the skin layer, does not show a surface tackiness, has a good compression set, and does not require a post cure of a long time.
