The most extensively used sector is Muscovite, and the 2nd is gold mica. It is commonly utilised in constructing content sector, hearth fighting industry, fire extinguishing agent, electrical welding rod, plastic, electrical insulation, paper creating, asphalt paper, rubber, pearlescent pigment and other chemical sector. Superfine mica powEPTcan be used as practical fillers such as plastics, coatings, paints and rubber to improve its mechanical power, toughness, adhesion, ageing resistance and corrosion resistance. In addition, corrosion, elasticity, toughness and sliding resistance and noise, minimal coefficient of thermal growth houses this sort of as large electrical insulation, and introduced the first two characteristics of sheet floor easy, diameter thickness ratio, typical form, strong adhesion. The principal use of EPT insulation and its warmth resistance, acid and alkali resistance, and compressive power and exfoliation of insulating material is utilised as electrical tools and electrical gear next for furnace window and EPTry production steam boiler, smelting furnace of the components
