Our wet ground mica powder use good quality mica material, in a manufacturing process with washing, refining, dipping, grinding and crashing, cold-drying, screening, and become a kind of good quality filler. Its unique manufacturing technique retains the mica flakes structure, redius-thickness ratio, higher index of refraction, higher purity, higher whiteness, higher luster, lower sand & iron content etc.
The performance of wet ground mica powder highly improve mica's application in resin and plastics (engineering plastics: PA66, PPR pipe), paint(corrosion protection), rubber, lubricant etc, improving the product performance and reducing the cost.
