There are many varieties of high temperature vulcanized silicone rubber, which can be divided into: methyl silicone rubber, methyl vinyl silicone rubber, phenyl silicone rubber, methyl ethyl silicone rubber, fluorosilicone rubber, nitrile silicone rubber, main Silicone rubber containing fluoroalkylene in the chain, silicone rubber containing arylene and aryl ether in the main chain, silicone rubber containing fluoroalkylene in the main chain, silicone rubber containing fluoroarylene in the main chain, silicone rubber containing fluoroarylene in the main chain Silicone rubber of carbodecaborane, silicone rubber containing cyclodisilazane in the main chain, etc., and thermoplastic silicone rubber of polydimethylsiloxane and polycarbonate block copolymerization, polydimethylsiloxane and polyarylene Ester block copolymerized thermoplastic silicone rubber, polydimethylsiloxane and polystyrene block copolymerized thermoplastic silicone rubber, etc. modified silicone rubber. Some of them can improve the cold and heat resistance of silicone rubber; some can improve the oil and solvent resistance of silicone rubber; some can improve the physical and mechanical properties and radiation resistance of silicone rubber; Some can make the silicone rubber have good high reversion and high temperature solvent resistance; some can make the silicone rubber resistant to high temperature, oil and radiation; the thermoplastic silicone rubber modified by block copolymerization is composed of poly It is composed of methyl siloxane and linear organic polymer. It has the characteristics of phase separation. It exhibits two glass transition temperatures. It can be processed into various rubber products by the processing method of thermoplastics. Excellent physical and mechanical properties. It can maintain the characteristics of rubber in a wide temperature range. It is easy to use.
Mixed silicone rubber can be divided into general type, low compression set type, high temperature resistant type, low temperature resistant type, high strength type, fatigue resistant type, oil resistant type, radiation resistant type, heat shrinkable type, according to its use and characteristics. Conductive type, self-extinguishing type, self-adhesive type, non-two-stage vulcanization type, sponge type, and series of differentiated varieties for extrusion molding, model vulcanization, roller use, and medical use.
