Wollastonite 1. Form:needle, powder 2.Size:80 mesh to 1250 mesh 3.Use:paint,plastic,metallurgy,ceramic,rubber,building etc. WollastoniteWollastonite extensive use in oil paint, plastics, rubber, electric welding, glass, electron industry, metallurgy and paper making. Its insulation performance is very good, endure acid, resist abrade, bear high temperature, have good fibre performance. Refined mineral wollastoniteFeatures:1) high purity near the theoretic component2) good needle-shape, low ignition loss3) low content of harmful constituent such as fe2o3, s and pMain chemical components (%):
