Dry ground mica powder is produced by natural mica flakes without water washing. We select high quality mica flakes as the raw material to mechanical grinding. Our product has uniform particle size distribution, high purity, still maintain the natural characteristics of mica.
Dry ground mica powder is widely used in building materials, paint, coating, rubber, plastics, and other industrial industry with his unique acid and alkali resistance, chemical stability, heat resistant, incombustibility, best insulation and stable granularity.
Dry ground mica powder (size):
Crude powder: 900μm（20mesh）、450μm（40mesh）、300μm（60 mesh）；
Fine powder: 150μm（100 mesh）、75μm（200 mesh）、45μm（325 mesh）
