Wollastonite Powder
Chemical name: Acicular Wollastonite Powder
Molecular formula: CaSiO3
Properties: Wollastonite is a kind of metasilicate mineral with calcium. The pure wollastonite powder is white, and is grey or brown if mixed with impurity. The crystal is acicular or granular with vitreous luster. It has excellent insulation property, thermal resistance, good chemical stability, very high dielectric property, low water and oil absorption.
Use: It can be used in pigment industry in place of the expensive titanium white powder, to produce high-quality white paint and color mild paint and coating, and can also used in the filler of rubber, plastics and resin.
Packing: Composite plastic woven bag; 25kg/bag.
