Mica sheet Rigid is also named as mica plate, or mica board. It’s made of 90% mica paper bonded with 10% high-temperature silicone resin, heated and pressed to the rigid sheet thickness from 0.1mm ~100mm, the most popular thickness is 0.3~1.5mm. The gray color is Muscovite Rigid Mica Sheet, Phlogopite Rigid Mica Sheet is light brown and light green color, the white is Synthetic Rigid Mica Sheet. They are widely used as high-temperature electrical insulation materials.
