Abstract

Cured unitary molded articles containing conductive and insulating silicone rubber components are prepared by tightly contacting a curable insulating silicone rubber composition comprising a curable silicone rubber containing substantially no carbon black and a nonacyl-type peroxide with a cured conductive silicone rubber component containing carbon black and which has been cured by an addition reaction in the presence of a platinum-type catalyst and molding the resultant composition at elevated temperatures to cure the insulating silicone rubber component and form a unitary cured silicone rubber article. This invention also relates to cured silicone rubber articles prepared using the method of this invention.
