Manufactured from the purest muscovite mica, by a slow, frictional delamination process, this unique mica powder finds a wide variety of applications in industries like rubber, plastics, paints and cosmetics.
PREMICA™ wet ground mica is processed in ceramic lined mills to prevent metal contamination, thereby ensuring a product of the highest purity. The PREMICA™ wet ground mica conforms to ASTM standards (D-607-75).
PREMICA™ increases flexural strength and modules, raises heat deflection temperature and reduces wrapage and shrinkage. As a result, PREMICA™ is in great demand as a filler, especially where thermal and structural stability are important considerations.
PREMICA™'s natural sheen and lustre coupled with the advantages of being non-toxic and non-carcinogenic, makes it an excellent raw material in the cosmetics, paints, plastics and pigments manufacturing industries.

PREMICA™-ACL is a super-fine grade of wet ground mica, with an average particle size of 2 - 5 microns. This distinct product from PMC is intended for high-end, specialised applications in industries.
The above regular grade mica products are also available as PREMICA™ (W), which has whiteness, L>80 Minolta. This product has a much whiter colour and hence finds great importance in the paints and cosmetics industries. The specifications of PREMICA™ (W) are the same as that of our regular grades.
In addition to the above regular grades of wet ground mica, PMC also produces custom grade mica designed to meet the specific requirements of our individual clients. If you are looking for mica products, which should meet certain specifications for your industry, please contact us with your requirements. We are sure that we can match your expectations and deliver world class mica as per your requirements.
