Abstract
An electrically conductive liquid silicone rubber composition comprises (A) 100 parts by weight of an organopolysiloxane having a viscosity of 10-100,000 centipoise at 25° C., (B) 1-100 parts by weight of a finely divided silica powder, (C) 30-700 parts by weight of a metal powder or an electrically conductive metal-plated powder, and (D) a curing agent in an amount sufficient to cure the organopolysiloxane. The composition has a low volumetric resistivity, a stable electrical resistance and can be injection-molded and cured to give an outstanding silicone rubber that is useful in electrical components and electrical contacts employed in high-conductivity applications.
