Abstract
A silicone rubber composition comprising an organopolysiloxane component composed of (A) an organopolysiloxane gum having an alkenyl content of 0.001-2 mol % and (B) an organopolysiloxane gum having an alkenyl content of more than 2 mol % to 20 mol %, (C) microparticulate silica, (D) platinum or a platinum compound, (E) an organosilicon compound containing a nitrogenous organic group and an unsaturated hydrocarbon group and/or a benzotriazole, and (F) a curing agent cures into electrically insulating silicone rubber having a minimized tensile permanent set, improved mechanical strength, and tracking resistance.
