ABSTRACT:
In a semiconductive silicone elastomer composition comprising an organopolysiloxane containing at least two aliphatic unsaturated hydrocarbon groups attached to a silicon atom, an organohydrogenpolysiloxane containing at least two hydrogen atoms attached to a silicon atom, and a conductive agent, the conductive agent consists of 1-10 wt % of conductive carbon and 99-90 wt % of a conductive filler having a volume resistivity of 10.sup.1 -10.sup.8 .OMEGA.-cm other than the conductive carbon. The conductive agent is blended in an amount of 20-60 wt % of the entire composition. The composition having the conductive agent uniformly dispersed therein yields a semiconductive silicone elastomer having a volume resistivity of 10.sup.5 -10.sup.10 .OMEGA.-cm with a dispersity of 1 to 10.
