building material grade mica powder

Muscovite mica is high purity muscovite powder produced by grinding crushing and shearing technique without changing any property. During the whole production, we adopt total enclosed filling system to make sure the product quality and meet the requirement of environmental protection. The screening process uses patent technique ensuring the stability of quality and well-distributed particle, so we can guarantee the quality for the customers higher purpose.

Muscovite mica has better insulating property, heat-resistance, acid & alkali-resistance as well as lower heat expansion coefficient. But the differences are muscovite powder(plastic grade) improving the purity and whiteness. It is widely used for fillers of cosmetics,plastics, ceramics, rubbers , coatings etc.
