hot vulcanized silicone rubber (RTV) : hot vulcanized silicone rubber, also known as high temperature vulcanized silicone rubber, where the molecular weight between 500,000 and 800,000 straight chain siloxane are high temperature vulcanized silicone rubber, RTV for short. Usually with octylcyclotetrasiloxane (D4) as the main raw material under the catalytic action of acid or alkali ring-opening polymerization of raw rubber, and then by using oxide as cross-linking agent, and with a variety of additives (such as reinforcing filler, heat stabilizer, structure control agent, etc.), in the rubber mixer mixing into homogeneous mixing agent, Then, by means of molding, extrusion, calendering and other high temperature vulcanization into a variety of rubber products.
