ABSTRACT:
The electroconductive silicone rubber composition of the invention is prepared by compounding a diorganopolysiloxane with each a specified amount of spherical particles of a cured silicone elastomer, metallic electroconductivity-imparting agent, e.g., metal powder, and a curing agent, e.g., organic peroxide. The composition has good molding workability and is capable of giving a cured electroconductive silicone rubber body having good mechanical properties along with high electroconductivity despite the formulation including the metal powder. Improvements can be obtained in the elastic resilience and permanent compression set of the cured silicone rubber body by the admixture of the composition with a specific liquid organosilicon compound having a phenyl group or an alkyl group of 3 to 10 carbon atoms bonded to the silicon atoms.
