Abstract:
1. A heat-conductive silicone rubber composition comprising: (A) 100 parts by weight of an organopolysiloxane containing an average o at least 0.1 alkenyl groups bonded to silicon atoms within each molecule and with a viscosity at 25° C. within a range from 50 to 100,000 mPa·s, (B) an organopolysiloxane containing an average of at least 2 hydrogen atoms bonded to silicon atoms within each molecule and with a viscosity at 25° C. within a range from 1 to 100,000 mPa·s, in a sufficient quantity to produce 0.1 to 3.0 mols of silicon atom-bonded hydrogen atoms within said constituent (B) per 1 mol of silicon atom-bonded alkenyl groups within said constituent (A), (C) 100 to 2,500 parts by weight of a heat-conductive filler, (D) an effective quantity of a platinum catalyst, and (E) 0.1 to 30 parts by weight per 100 parts by weight of said constituent (C) of a methylpolysiloxane with a hydrolyzable group and a vinyl group, as represented by a general formula (I): wherein, R represents a monovalent hydrocarbon group of 1 to 4 carbon atoms, R
