ABSTRACT:
A thick, highly filled, shaped elastomeric body comprising a thermally conductive elastomer suitable for high temperature, e.g. 240.degree.-260.degree. C. mechanical applications. The elastomer composition comprises organopolysiloxane, particulates, and a viscosity modifier. The organopolysiloxane crosslinks between the vinyl or allyl functionality of an organopolysiloxane polymer, and the silyl hydride functionality of an organopolysiloxane oligomer. The particulate comprises silica as well as a thermally conductive alloy powder of first row transition elements. The addition of a viscosity modifier comprising silicone oil is essential to the inclusion of the high levels of particulates.
