Industry:

plastics, resin, paint, ceramics, rubbers, demoulding, coating, sun-proof, antifreeze, building materials, fire-proof, decoration, corrosion protection, heat preservation etc

Details:

8~20 mesh is mainly used for building materials, playing an important part in water-proof, fire-proof, heat preservation, heat insulation and decoration.

40~60 mesh is well used for filler to improve the product usability.

60~120 mesh is available for paint admixture, filler, covering agent and rubber lubricant, plastic filler. Moreover, it is also the basic materials of mica ceramics.

200~325 mesh is widely used for pearl pigment.
