wollastonite in powder

Wollastonite is a kind of inorganic needle like mineral, the non-toxic, resistant to chemical corrosion, thermal stability and dimensional stability good, glass and pearl luster, low water absorption and oil absorption value, mechanical properties and electrical properties and excellent with must fill strong role. Wollastonite products of the company, fiber length and easy separation and low iron content, high whiteness, known not only domestic, in Europe and East Asia is famous, the product is mainly used as polymer matrix composite reinforcing filler. Such as plastics, rubber, ceramics, building materials and other industries.
