Wollastonite powder, with needle like and fibrous crystal morphology, high whiteness and unique physical and chemical properties, is widely used in ceramics, paints, coatings, plastics, rubber, chemicals, paper making, welding electrodes, metallurgical protection slag and as a substitute for asbestos.

Wollastonite powder not only plays a filling role in the plastic industry, but also can partially replace asbestos and glass fiber as reinforcement materials. At present, it has been applied in various plastics such as epoxy, phenolic, thermosetting polyester, polyolefin, etc. Wollastonite powder is widely used in the plastics of deep processing products. As a plastic filler, it is mainly used to improve tensile strength and flexural strength, and reduce costs.

In the rubber industry, natural wollastonite powder has a special needle like structure, white, non-toxic, and is an ideal filler for rubber after ultra-fine crushing and surface modification. It can not only reduce the production cost of rubber products, but also improve the mechanical properties of rubber and endow rubber with special functions that it does not have.

In the coating industry, wollastonite powder, as the filler of paint and coating, can improve the physical and chemical properties of products, durability and weather resistance, reduce the gloss of paint, enhance the expansion ability of coating, reduce cracks, and also reduce oil absorption and enhance corrosion resistance. Wollastonite has bright color and high reflectivity, which is suitable for producing high-quality white paint and clear and transparent colored paint. Acicular wollastonite powder has good flatness, high color coverage, uniform distribution and UV resistance. It is widely used in interior wall coatings, exterior wall coatings, special coatings, and latex coatings. Ultrafine particle size, higher whiteness and pH value, better paint color and coating performance, and alkaline paint can be used as a anti-corrosion coating for metal equipment such as steel.

In the paper industry, wollastonite powder can be used as filler and plant fiber to make paper composite fiber instead of some plant fiber. Reduce the amount of wood pulp used, reduce costs, improve paper performance, improve smoothness and opacity of the paper, improve uniformity of the paper, eliminate static electricity in the paper, reduce shrinkage of the paper, have good printability, and can reduce pollution emissions during the plant fiber pulping process.
