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.PREMICAâ„¢ wet ground mica is processed in ceramic lined mills to prevent metal contamination, thereby ensuring a product of the highest purity. The PREMICAâ„¢ wet ground mica conforms to ASTM standards (D-607-75).PREMICAâ„¢ increases flexural strength and modules, raises heat deflection temperature and reduces wrapage and shrinkage. As a result, PREMICAâ„¢ is in great demand as a filler, especially where thermal and structural stability are important considerations. PREMICAâ„¢'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.
