Main features and uses of silicone rubber products

Silicone rubber products are made of methyl vinyl silicone rubber as the base rubber, with various fillers (reinforcement agents, heat-resistant agents, modifiers, etc.) added and made through mixing, thinning, filtering, vulcanization, molding, extrusion, bonding and other production processes. Vulcanized rubber products have the following characteristics: (1) High and low temperature resistance: It can be used for a long time at 200°C and still be elastic at -60°C; (2) Electrical insulation performance: The dielectric properties of silicone rubber are excellent, especially the dielectric properties at high temperatures are much better than those of general organic rubber, and the dielectric strength is almost unaffected by temperature in the range of 20-200°C. (3) Excellent weather resistance, ozone resistance and ultraviolet radiation resistance, and no cracking occurs when used outdoors for a long time. It is generally believed that silicone rubber can be used outdoors for more than 20 years. (4) Excellent high-temperature compression permanent deformation. (5) Good processing performance, easy molding and other advantages, various products can be made through extrusion hot air vulcanization molding, mold addition molding, and extension molding. Due to the excellent comprehensive performance and good technical and economic effects of silicone rubber products, they have been widely used in aviation, aerospace, atomic energy, electrical appliances, electronics, instruments, automobiles, machinery, metallurgy, chemical industry, medical care, and daily life.
