Abstract
A heat-resistant silicone rubber is obtained from a composition of a vinyl-containing polyorganosiloxane, a hydrogenpolyorganosiloxane, a platinum-containing catalyst, carbon black, and an acetylacetone salt of a metal wherein the metal can be copper, zinc, aluminum, iron, cerium, zirconium, or titanium. The silicone rubber can maintain its rubber properties at temperatures of 350.degree. C. for prolonged periods of time.
