MICA-MU®, MICA-SOFT®

MICA-MU® and MICA-SOFT® are natural and white muscovite mica (alumino-silicate). These performant minerals have an excellent platelet structure, exceptional electrical properties and resist practically to all chemical materials

MICA-MU® is a dry ground muscovite mica available in different grain sizes : from 500 mm to 3 mm. This mica is especially recommended when whiteness or coloration are important factors (paints, plastics…)

MICA-SOFT® is a wet ground muscovite mica available in different grain sizes (from 40 mm to 10 mm). Its wet grinding process preserves the natural luster and sheen and permits to reach a higher lamellarity. This mica is particularly recommended for plastics reinforcement and acts also as a releasing agent in many type of moulds.
