Abstract The present invention provides an improved heat curable silicone composition, having increased tear strength, oil resistance, and reduced compression set, comprising (A) a blend containing (1) a vinyl-containing organopolysiloxane or vinyl-containing organopolysiloxane blend having a viscosity of about 5,000 to about 500,000 centipoise at 25 DEG C, and (2) a vinyl-containing organopolysiloxane or vinyl-containing organopolysiloxane blend having a viscosity of about 8,000,000 to about 100,000,000 centipoise at 25 DEG C; (B) an organopolysiloxane resin copolymer; (C) an organic peroxide catalyst; (D) a filler; and (E) an organohydrogenpolysiloxane.
