dry ground mica powder

dry ground mica powder √Ourmica powder is 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 . √Mica 100mesh is available for paint admixture, filler, covering agent and rubber lubricant, plastic filler. Moreover, it is also the basic materials of mica ceramics.
