Mica board has excellent insulation and high temperature resistance, which can be used for a long time at 1000 ℃. Widely used in metallurgy, chemical industry, home appliances and other industries, such as home hair dryer, electric iron, heating coil, hair curler, electric comb, power frequency furnace, intermediate frequency furnace, electric arc furnace, steel furnace, submerged arc furnace, ferroalloy furnace, electrolytic aluminum, motor insulation of injection molding machine, etc. It is a kind of hard or soft plate insulation material made of mica paper and high performance silicone resin by bonding, heating and pressing. The mica content is about 90% and the silicone content is 10%.

Compared with common insulating materials, mica board has the following outstanding advantages:

Excellent insulation at high temperature. At 500-1000 ℃, the breakdown resistance index is still 15 kV / mm;

Hard mica board has good bending strength and hardness, while soft mica board has good tensile properties, which can be processed into various shapes without delamination;

Excellent environmental performance, the product does not contain asbestos, smoke smell is small when heated, even smokeless and tasteless;

It has excellent acid resistance, alkali resistance and oil resistance.
