Rigid Mica Sheet tech date

Rigid mica sheet is mica paper as the base material, bonded with high temperature resistant silicone or epoxy resin, baked and pressed by high temperature. It has excellent electrical insulation and high temperature resistance. Hard mica plate for electric heating equipment can be used for a long time at a high temperature of 500℃-700℃. Mainly used for ovens, hair dryers, irons, toasters, microwave ovens, electric wire heaters, wall plate heaters and as heating brackets and linings for the above electrical appliances Pads, partitions, commutators, etc., And widely used in metallurgy, chemical industry, household appliances and other industries. Thick mica plate can be processed into various parts by turning, drilling, grinding, milling, etc. It is used in steel, metallurgy, petroleum, locomotive, military industry, shipbuilding and other industries and fields.
