ABSTRACT:
The invention comprises a thermally conductive elastomer suitable for high temperature, e.g., 240.degree.-260.degree. C., mechanical applications. The elastomer composition comprises organosiloxanes, particulates and a viscosity modifier. The organosiloxane crosslinks between the vinyl or allyl functionality of an organopolysiloxane polymer and the silyl hyride functionality of an organopolysiloxane oligomer. The particulate comprises silica as well as a thermally conductive carbon powder. The addition of a viscosity modifier comprising silicon oil is essential to the inclusion of the high levels of particulates.
