<p>A silicone rubber sponge composition, a silicone rubber sponge, and a process for production thereof. The silicone rubber sponge composition, comprises (A) 100 parts by weight organopolysiloxane gum described by average structural unit R<Sub>a</Sub>SiO<Sub>(4-a)/2</Sub>, where R is a monovalent hydrocarbon group or haloalkyl and a is 1.8 to 2.3 and having a viscosity at 25°C of 1,000,000 mPa · s or above, (B) 1 to 400 parts by weight inorganic filler, (C) 0.01 to 50 parts by weight hollow thermoplastic resin particles, (D) 0.1 to 10 parts by weight thermally decomposable blowing agent, and (E) a curing agent in an amount sufficient to cure the composition.</p> |
