Wollastonite for Plastic

Wollastonite, as an important emerging non-metallic mineral, is widely used in ceramics, chemical industry, metallurgy, papermaking, plastic coating and other fields. After years of development, China has become the largest country in the international market for wollastonite resource production. 

In the plastic industry in the silicon ash powder filling effect not only, but also partly replacing asbestos and glass fiber used to enhance the material Currently, it has been in all kinds of plastic such as epoxy phenolic thermosetting polyester polyolefin in application of silicon ash powder are extensively used in plastic processing products It as a plastic packing, is mainly used to improve the tensile strength and flexural strength, reduce the cost Wollastonite is also widely used as a filler in polypropylene polystyrene polyethylene based chloride polyethylene. Compared with other fillers, adding wollastonite to polystyrene resin synthesis can reduce the amount of expensive color without affecting the quality Because wollastonite has low moisture content, light color with luster, stable shape, and reinforcement properties, it is often used in nylon molded materials and wollastonite powder is used in the sole of rubber shoes industry, replacing part of titanium dioxide white carbon black clay, etc., the effect is good for improving the product quality of rubber hose tape, and the cost is significantly reduced.
