ELECTRICALLY CONDUCTIVE SILICONE RUBBER COMPOSITION AND ELECTRICALLY CONDUCTIVE SILICONE RUBBER SPONGE

摘要

PROBLEM TO BE SOLVED: To provide an electrically conductive silicone rubber composition safely giving an electrically conductive silicone rubber sponge of high expansion ratio without the need of long-time postcuring, and to provide the electrically conductive silicone rubber sponge obtained by expanding and curing the above composition.;SOLUTION: The electrically conductive silicone rubber composition comprises (A) 100 pts.mass of an alkenyl group-containing organopolysiloxane containing in one molecule 10-500 ppm, on a mass basis, of CH₃SiO_1.5 units, (B) 1-100 pts.mass of electrically conductive carbon black, (C) 0.01-50 pts.mass of a foaming agent generating a gas at 90°C or higher and (D) an organic peroxide. The electrically conductive silicone rubber sponge obtained by expanding and curing the above composition is also provided.;COPYRIGHT: (C)2008,JPO&INPIT
