Injection molding grade silicone rubber silica particles, silica particles characteristic use injection molding grade injection molding grade silicone particles of silica particles of silicone rubber silicone rubber silicone characteristic use of silicone injection silicone silicone rubber with excellent heat resistance, cold resistance, dielectric properties, resistance to ozone and atmospheric aging properties, outstanding performance of silicone rubber is wide operating temperature can be at -60 ℃ (or lower) to + 250 ℃ (or higher) under long-term use. But the tensile strength and tear strength and other mechanical properties of silicone rubber is poor, at room temperature is less than most of its physical and mechanical properties of synthetic rubber and nitrile addition to silicon, fluorosilicone rubber, generally silicon rubber oil resistance, solvent resistance poor, it is not appropriate for the occasion of ordinary silicone rubber condition, but very suitable for many special occasions. Silicone rubber (English name: Silicone rubber), Heat and vulcanized (HTV silicone HTV), room temperature vulcanized (RTV), which was divided RTV condensation reaction type and an addition reaction type. High-temperature silicone rubber is mainly used in the manufacture of silicone rubber products, while room temperature silicone rubber is mainly used as adhesives, potting materials, or the use of molds. The largest amount of heat curing type, heat curing was divided methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, dosage and product brands the most), methyl phenyl vinyl silicone rubber PVMQ (low temperature resistance, radiation ), there are other eye silicone rubber, fluoro silicone rubber.
