Wet ground mica powder

Wet ground mica powder has the characteristics as follows: high insulating strength, large resistance, strong mechanical strength, high temperature resistance, acid and alkali resistant.

Our wet ground mica powder is produced by natural good quality white mica ore as raw material, with a unique manufacturing process: winnowing subtraction, water soak, grinding, drying, high pressure comminution, grading screen. The mica flake structure is greatest protected by unique production process, so it has the advantages of large diameter thickness ratio (HAR), good dispersion, good luster, high purity and so on.
