Mica sheet is a flat insulating material made of natural mica flakes, mica paper or synthetic mica materials through pressure, heating and other processes. It usually has good mechanical strength, electrical insulation, high temperature resistance and corrosion resistance, so it is widely used in equipment requiring high temperature, insulation and fire protection requirements.
