muscovite

MuscoviteMuscovitebelongs to phyllosilicate minerals that are derived from the earth's crust.It consists of numerous elements in the earth. It takes many years to form in a high temperature and pressure environment. Many kinds of mica exit with compositions consisting of a complex variety of chemical components. It has a unique acid resistance, alkali resistance, chemical stability, but also has good insulation and heat resistance, non-flammable, corrosion resistance, heat resistance and flexibility, tensile resistance, aging resistance and so on. According to the different manufacturing processes, the mica powder is divided into dry ground mica powder, wet ground mica powder, and ultra-white mica powder. It is mainly used for paint of inner and outer of wall in Architecture,coating of corrosion resistance,paint of hign temperature resistance,coatings of fire-proof,rubber,plastics,welding rod,damping board,brake pad,sealed material,fire-fighting equipment,building material,drilling mud,pearluster pigment,insulation material and other fields.
