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.
