1. The product description

Enhanced Wollastonite fibers is made of natural silica limestone by advanced grinding technology and modification process, Its main component is calcium silicate, its molecular type is CaSiO3. Wollastonite mohs hardness is 4.5 ~ 5.5, Its proportion is 2.78 ~ 2.91, melting point is 1540 ℃,its thermal expansion coefficient is low. Wollastonite has fine insulation performance,dielectric performance, high heat resistance and weather resistance. It is widely used in ceramics,chemical industry, metallurgy, papermaking, plastics, coatings, rubber and other fields.

3. Product features

Wollastonite acicular fiber structure is the only a pure white filling material, the length to diameter ratio from 3:1 to 20:1, this kind of high needle shape can be used to enhance the adhesion of coating, which can make the coating has better mechanical strength, persistence, and weather resistance to prevent the cracking.

In plastics, It can improve the electric insulation, impact strength and tensile strength of products,and it can improve the linear stretching and die shrinkage of products. It can replace the traditional glass fiber partially or completely to offer strengthening significantly. The maximum dosage can reach 30-50% in PP.

Wollastonite is a good filling material in rubber products to strengthen rubber liquidity and improve the tensile strength and tearing strength, impact strength, the linear stretching and mold shrinkage, to make the products of the aging resistance and fatigue resistance improved.
