Hard mica board is based on mica paper and bonded with high temperature resistant silicone resin. It is a plate-shaped insulating and temperature resistant material baked and pressed at high temperature. It has excellent electrical insulation and high temperature resistance. The hard mica plate for electric heating equipment can be used for a long time at a high temperature of 500-700 degrees. It is mainly used in ovens, hair dryers, electric irons, toasters, microwave ovens, electric wire heaters, wall panel heaters, as well as heating brackets, cushion diaphragms, commutators for the above appliances. It is widely used in metallurgy, chemical industry, household appliances and other industries.
