Abstract
A thixotropic agent is blended in a silicone rubber composition comprising an alkenyl radical-containing organopolysiloxane, an organohydrogenpolysiloxane, an addition reaction catalyst, and filler balloons having a specific gravity of 0.01-0.40 and a mean particle size of 1-300 .mu.m. The resulting composition effectively restrains floating and separation of the filler, remains stable and is thus suitable for injection molding.
