White Wollastonite Powder is used widely in plastic, ceramics, rubber, and paint industries to enhance surface color, tensile strength, and heat performance of products. High brightness and whiteness, low volatile content, low moisture, and oil absorption are some of its features that make sit high on demand. Chemical Formula : CaSiO3 PHYSICAL PROPERTIES : Appearance- White fine powder Sp. gravity- 2.8 - 3.0 PH Value- 8.0 - 8.5 Fineness- Passes 325 mesh CHEMICAL COMPOSITION : SiO2 Content- 6 5% Iron Content- 0.5% Water Content- 1% Industrial Applications : Used as Filler In Rubber, Plastics, Electric insulators, powder coatings etc.
Wollastonite is chemically a Calcium Meta Silicate (CaSiO3), it is a naturally occurring white & acicular (needle shaped) mineral, with mohs hardness of 4.5. In addition to Wollastoniteâ??s unique morphology, it is alkaline, inert, has low loss on ignition, low water solubility, low co-efficient of linear thermal expansion and a melting point of 15400c. It also improves tear strength, dielectric properties and retains mechanical properties at elevated temperatures.

Description: Wollastonite has bright color and high reflectivity, which could be suitable for the production of high-quality white paints and clear transparent paints.wollastonite is a good additive with higher fraction of color coverage and homogeneous distribution. Based on its UV resistance, it is widely used in interior wall paints, exterior wall paints, special paint (especially fireproof paint) and latex paints. Wollastonite powder which can partly replace titanium dioxide to produce paint coating can not only improve the color of products, improve the gloss of the paint, enhance the anti-tensile ability of the paint, reduce the crack, but also can reduce the oil absorption and enhance the anti-corrosion ability. The finer particle size, higher whiteness and pH value can greatly improve the color and coating property of the paints, which can be helpful to produce anticorrosive coating for metal equipment such as steel pieces. Wollastonite can also be used as the filler of paint coating to improve the physical and chemical properties, durability and weather resistance and reduce the fracture and aging of the paint. The quality requirements of wollastonite in paint coatings are: SiO2 49%min, CaO 45%min, Fe2O3 0.2%, 325 mesh, mineral powder oil absorption amount is 20-25g/100g, water soluble matter 0.5%, water extraction pH value is 7-9, whiteness 90%.
