The mica sheet is made of high-quality muscovite paper or phlogopite paper as raw materials, and is a hard plate-shaped insulating material formed by bonding with high-temperature silicone resin after baking and pressing. It has excellent insulation properties and high temperature resistance, and can be used for a long time at a high temperature of 500-800℃.
1, Excellent high temperature resistance and insulation performance, the highest temperature resistance is as high as 1000 ℃.
2, Excellent electrical insulation performance. The voltage breakdown index of ordinary products is as high as 20KV/mm.
3, Excellent bending strength and processing performance. The product has high bending strength and excellent toughness. It can be processed into various shapes without delamination.
2.Widely used in metallurgy, chemical industry, household appliances and other industries, such as household ovens, toasters, toasters, microwave ovens, hair dryers, electric irons, heating coils, curling irons, electric combs, industrial electric furnaces, power frequency furnaces, refining frame materials for electric heating equipment such as furnaces, intermediate frequency furnaces, calcium carbide furnaces, electric arc furnaces, power plants, electrolytic aluminum, injection molding machines, etc.
