Abstract: The inventive foamable silicone rubber composition comprises (a) a silanolic hydroxy-terminated diorganopolysiloxane, (b) a vinylsilyl-terminated diorganopolysiloxane, (c) an organohydrogenpolysiloxane as a crosslinking agent of the diorganopolysiloxanes, (d) a filler, (e) a platinum compound as a catalyst, (f) aluminum hydroxide and (g) red phosphorus. The components (f) and (g) each serve as a fire-resistance improver to synergistically impart the cured foamed silicone rubber with greatly improved resistance against fire when it is exposed to flame.
