摘要： A foamable silicone rubber composition comprising (A) a diorganopolysiloxane having a viscosity of at least 10.sup.6 cs at 25.degree. 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.

摘要： A silicone rubber composition comprising (A) an organopolysiloxane, (B) an inorganic filler, typically fumed silica, and (C) a specific halogen-free organic peroxide, typically 1,6-bis(p-toluoylperoxycarbonyloxy)hexane or 1,6-bis(benzoylperoxycarbonyloxy)hexane is safe and lends itself to atmospheric hot air vulcanization so that it can be extrusion vulcanized into silicone rubber having satisfactory physical properties without voids or surface tack. The silicone rubber composition is extrusion molded around an electrical wire, constructing a covered wire.
