Mica

Muscovite Mica is a hydrated silicate of potassium and aluminium. Anglo Pacific Minerals can supply Indian and Chinese dry ground and micronised powders. Mica has a multitude of Applications but the main applications are in paint, plastics, construction, fire retardency, sound proofing, welding rods and oilfield drilling.

Applications:
Paint, plastics, construction, fire retardants, sound Proofing, welding rods, and oilfield drilling.
