FAQs of Wollastonite Powder:

Q: How is wollastonite powder typically used in industrial applications?

A: Wollastonite powder is primarily used as a functional filler and reinforcement material in ceramics, plastics, paints, rubbers, frictions products, and construction materials due to its high mechanical strength, low porosity, and dimensional stability.

Q: What are the benefits of using wollastonite powder in ceramics and plastics?

A: In ceramics and plastics, wollastonite powder enhances mechanical properties, improves dimensional stability, and provides a smooth surface finish. Its low water absorption and chemical stability also contribute to the durability and performance of finished products.

Q: When should you choose wollastonite powder with a particle size up to 325 mesh?

A: You should opt for wollastonite powder with up to 325 mesh particle size when a fine dispersion, smooth surface finish, and optimal reinforcement characteristics are required in formulationsfor example, in paints, coatings, and high-performance plastics.

Q: Where can wollastonite powder be sourced from?

A: Wollastonite powder can be sourced from reputable manufacturers, exporters, and suppliers in India, who provide secure packaging in 25 kg, 50 kg HDPE bags or jumbo bags for both domestic and international markets.

Q: What process is followed to ensure the quality of wollastonite powder?

A: The manufacturing process involves precise selection, crushing, and micronization of the mineral, followed by rigorous quality checks for chemical composition, particle size distribution, moisture content, and loss on ignition to guarantee consistency and performance.

Q: How does the low water absorption of wollastonite benefit end products?

A: Low water absorption in wollastonite powder helps maintain the integrity, mechanical strength, and durability of finished products, especially in construction and polymer applications where moisture resistance is vital.
