2. Product characteristics
Methyl vinyl silicone rubber is a colorless, transparent, non-toxic and odorless colloid. An appropriate amount of reinforcing agent, structure control agent and vulcanizing agent (or catalyst and crosslinking agent) are added to the raw rubber to make the mixed rubber. The compound can be processed into various silicone rubber products by molding, extrusion and casting. Silicone rubber vulcanizate has excellent high and low temperature resistance and can be used for a long time in the temperature range of - 60 ~ 250 ℃. It has weather aging resistance, ozone resistance, radiation resistance and good chemical stability. Silicone rubber also has excellent electrical insulation performance, hydrophobicity, moisture resistance, earthquake resistance and physiological inertia. If some other additives are added to the compound, the vulcanizate can also have many new characteristics.
3. Product use
Methyl vinyl silicone rubber vulcanizates are widely used in aerospace, electronic and electrical, metallurgical machinery, transportation, instrumentation, textile light industry, food and medicine and other industrial departments. They are widely used as wire insulation, high temperature resistant sealing gasket and conduit; Anti sticking rubber roller; Conductive rubber products, etc. the application of silicone rubber can greatly improve the reliability and safety of these products. Silicone rubber is also widely used in the field of medical and health care.
Methyl vinyl silicone rubber is copolymerized by dimethylsiloxane and a small amount of vinyl siloxane. The introduction of a small amount of unsaturated vinyl has greatly improved its vulcanization process and finished product properties, especially heat aging resistance and high temperature compression deformation resistance.Methyl vinyl silicone rubber vulcanizates are widely used in aerospace, electronic and electrical, metallurgical machinery, transportation, instrumentation, textile light industry, food and medicine and other industrial departments.
