Hardness Improving Calcium Carbonate Powder for Table Top Filling

Product Description

Company Profile

Product Description

Heavy calcium carbonate, derived from finely ground natural calcite, is a highly versatile mineral filler widely used in construction materials, coatings, plastics, and rubber industries. With a 325-mesh particle size, this powder offers an optimal balance of fine particle distribution, surface smoothness, and cost-effectiveness, making it an essential additive for enhancing product performance.

In putty powder formulations, 325-mesh calcite powder improves workability and crack resistance while ensuring a smooth, even finish on walls. Its high whiteness enhances paint adhesion and color retention, making it ideal for both interior and exterior applications.

For coatings, calcite acts as a functional filler that reduces raw material costs while improving key properties such as opacity, weather resistance, and anti-corrosive performance. Its fine particles contribute to better dispersion in liquid systems, ensuring uniform film formation and enhanced durability.

In the polymer industry, heavy calcium carbonate serves as a reinforcing filler for plastics and rubber. It increases tensile strength, impact resistance, and dimensional stability in products like PVC pipes, automotive parts, and rubber tires. Additionally, its low oil absorption minimizes compound viscosity, facilitating easier processing during extrusion, injection molding, or calendering.

With its natural abundance, non-toxic composition, and multifunctional benefits, 325-mesh heavy calcium carbonate remains a preferred choice for manufacturers seeking to optimize product quality while maintaining cost efficiency across various industrial sectors.
