Brief Introduction
Wollastonite is a kind of chain metasilicate mineral, triclinic crystal system, fine plate crystal, the aggregate is radial or fibrous. Its unique needle-like structure is used in modified plastics to enhance the mechanical strength, dimensional stability and improve the processing technology. As a high performance mineral modified material, wollastonite has a remarkable effect in various thermoplastic resin systems. Also wollastonite is widely used in high-grade coatings such as architectural coatings and industrial coatings.
Product Features
Low dielectric index and high mechanical strength.
The unique needle-like structure can improve the tensile strength, bending strength and other mechanical properties of the product.
High refractive index, but also to maintain the surface flat and gloss.
It can improve the scratch resistance, weather resistance and crack resistance of the coatings.
