Foamable silicone rubber composition and silicone rubber sponge.

摘要

A foamable silicone rubber composition comprising (A) a diorganopolysiloxane having a viscosity of at least 10<6> cs at 25 DEG C, (B) an organohydrogenpolysiloxane, (C) a platinum catalyst, (D) azodicarbonamide foaming agent, and (E) an acetylenic alcohol reaction controlling agent is foamed and cured, preferably through UHF vulcanization, into silicone rubber sponge. The sponge having satisfactory strength and foam properties is obtained without a hygienic problem.
