Abstract
A sponge-formable silicone rubber composition of the present invention comprises (A) a polyorganosiloxane having at least two silicon-bonded alkenyl groups per molecule, (B) a polyorganosiloxane having at least two silicon-bonded hydrogen atoms per molecule, (C) water, (D) a thickening agent, (E) an emulsifier, (F) a halogen-containing ion conductor of an alkali metal, and (G) a hydrosilylation reaction catalyst. The sponge-formable silicone rubber composition can form a silicone rubber sponge having uniform and fine bubbles and having small distortion due to contraction after secondary vulcanization.
