Wollastonite Powder Nature’s Multipurpose Mineral for Industrial Advancements

Short Description:

In paints and coatings, wollastonite serves as a functional extender, boosting opacity, weather resistance, and scratch resistance while reducing pigment usage. Its hydrophobic surface minimizes water absorption, making it suitable for exterior applications. The rubber industry utilizes wollastonite to reinforce tires and seals, improving tear strength and heat resistance. Additionally, wollastonite is used in friction materials (e.g., brake pads) for its ability to stabilize friction coefficients and reduce wear. Its high melting point and low thermal expansion also make it valuable in refractory applications.

Overall, wollastonite’s versatility, eco-friendliness, and cost-effectiveness position it as a key mineral in modern manufacturing.

Wollastonite

Details:

Wollastonite is a single-chain silicate mineral, the main component is Ca₃Si₃O₉. Triclinic crystal system, usually in the form of flakes, radial or fibrous aggregates. White with slight gray. Glass luster, pearl luster on the cleavage surface. Hardness 4.5-5.0 with density of 2.78-2.91g/cm³. Mainly produced in the contact metamorphic zone of acidic intrusive rock and limestone, it is the main mineral composition of skarn.

Prroduct Advantage:

Plastics industry:

In the plastics industry, wollastonite powder not only plays a filling role, but also partially replaces asbestos and glass fiber for reinforcing materials. Mainly used to improve tensile strength and flexural strength and reduce costs.

Rubber industry:

In the rubber industry, wollastonite powder is an ideal filler for rubber, not only can reduce the production cost of rubber products, but also can improve the rubber mechanical properties give special functions that rubber does not have.

Paints&Coatings industry:

In the coating industry, wollastonite powder is used as a filler for paints and coatings, which can improve the physical and chemical properties of the product, durability and weather resistance, reduce the gloss of the paint, enhance the expansion ability of the coating, reduce cracks, and can also reduce oil absorption and enhance corrosion resistance.
