<p>Heat curable elastomeric silicone rubber compositions are produced which exhibit good tear strength, compression set, good tensile strength, and excellent heat-age and oil resistance properties. The blend includes 1) a vinyl-stopped organopolysiloxane gum, 2) a silica filler, 3) an MQ or M-D vinyl-Q resin, or blends thereof , and 4) a cross-linking agent to produce a silicone elastomer which is heat curable in the presence of a peroxide catalyst and mixtures of groups 2A and 2B metal oxides including magnesium and zinc.</p> |
