ABSTRACT:
A thermally conductive silicone rubber composition comprised of (A) 100 parts by weight of an organopolysiloxane that contains at least two silicon-bonded alkenyl groups per molecule, (B) 0.1 to 50 parts by weight of an organohydrogenpolysiloxane that contains at least two silicon-bonded hydrogen atoms molecule, (C) 0.1 to 10 parts by weight of organosiloxane that contains at least one silicon-bonded alkoxy group per silicon-bonded hydroxyl per molecule, (D) 300 to 1200 parts by weight of fine alumina powder comprised of (i) 5 to 95 wt % of spherical or nonspherical fine powder of an average particle diameter of up to 10 .mu.m and of (ii) 95 to 5 wt % of spherical or nonspherical fine alumina powder of an average particle diameter of 10 to 50 .mu.m, and (E) a catalytic quantity a hydrosilylation reaction catalyst.
