mica powder for building plate

mica powder for building plate Mica powder is in competitive price. It is high purity mica 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. Our products have better insulating property, heat-resistance, acid & alkali-resistance as well as lower heat expansion coefficient. Particles are different according to different application, and mainly divided into four grades: coarse, medium, fine, superfine .8~20 mesh is mainly used for building materials, playing an important part in water-proof, fire-proof, heat preservation, heat insulation and decoration. 40~60 mesh is well used for filler to improve the product usability. 60~120 mesh is available for paint admixture, filler, covering agent and rubber lubricant, plastic filler. Moreover, it is also the basic materials of mica ceramics. 200~325 mesh is widely used for pearl pigment. Mica powder can be used for oil well drilling, coating for pouring casting, polishing paste for aluminum product, coating for electro galvanized tank,cosmetics filler, antifreeze additive & antisun additive, and the suspending agent of dry powder fire extinguisher.   Chemical index
