High quality white wollastonite powder for paint industry building materials

Short Description:

Wollastonite powder, a calcium – inosilicate mineral, features needle – like or fibrous crystal structures. This unique morphology gives it exceptional mechanical and physical properties, rendering it highly valuable across multiple industries.

In the plastics industry, wollastonite powder acts as a reinforcing filler. When added to plastics, it significantly enhances their tensile strength, flexural modulus, and dimensional stability. This makes plastic products more durable, heat – resistant, and suitable for applications like automotive parts, electrical enclosures, and household appliances.

In the paint and coatings industry, wollastonite powder improves the hiding power, weather resistance, and scratch resistance of paints. It also helps prevent pigment settling, ensuring consistent color and texture. As a result, it is used in a wide range of coatings, from exterior house paints to high – performance industrial coatings.

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.
