Calcium Silicate Board Series – Wollastonite Powder

Our company’s high-quality wollastonite needle-shaped powder series is primarily used as an additive in fire-resistant, environmentally friendly calcium silicate boards. Despite undergoing mechanical grinding, its unique needle-like structure remains intact and well-preserved. Calcium silicate boards containing wollastonite powder not only exhibit excellent fire resistance but also boast superior flexural and fracture strength. They are lightweight yet maintain their structural integrity under heavy loads. Moreover, wollastonite is non-toxic, odorless, and poses no radiation hazards to humans, making it an outstanding choice for natural, eco-friendly building materials! Currently, this product is exported to markets across Southeast Asia and has received unanimous acclaim from customers who prioritize fire safety and public security!

Wollastonite Powder for Friction Materials Series

Even after repeated mechanical grinding, wollastonite still maintains its well-balanced and uniform aspect ratio. Its naturally needle-like structure significantly enhances the wear resistance of brake pads and improves product quality! The average aspect ratio of this product can reach 20:1, providing a strong guarantee for the safety factor of vehicle operation!

Plastic Filler Series: Wollastonite Powder

Adding wollastonite powder to plastics can improve the tensile strength and flexural strength of plastic products, reduce the amount of resin required, and enhance the thermal stability and dimensional stability of plastics at high temperatures. Needle-shaped wollastonite powder, after surface treatment, can increase the adhesion between wollastonite and organic polymers, thereby improving the properties of molded products. Wollastonite is widely used in automotive plastics, as well as in PP, PV, PVC, and other plastic products. Currently, the automotive plastics market has become the fastest-growing consumer sector for wollastonite.

Interior wall tiles with wollastonite raw material added

The appropriate addition of wollastonite can significantly reduce the firing temperature and shorten the firing time of ceramic bodies, thereby effectively saving energy consumption. During ceramic firing, wollastonite helps minimize shrinkage, markedly improves the flexural strength and crack resistance of the products, and enhances their mechanical strength. As a result, it boosts product yield and economic benefits, earning widespread acclaim from ceramic customers!
