About this product

Product information from the supplier.

Industrial Grade Ground Calcium Carbonate (GCC) is a premium functional inorganic filler engineered from high-purity natural carbonate minerals, including calcite, marble, and limestone. Renowned for its exceptional chemical purity, thermal stability, and high whiteness, GCC serves as a critical raw material for enhancing the physical and chemical properties of industrial compounds while ensuring structural integrity.

Designed for versatility, our GCC is optimized for seamless integration into rubber, plastics, paints, and construction materials. By providing superior dispersibility and low oil absorption, it allows manufacturers to achieve precise control over material viscosity and texture, making it an indispensable solution for high-performance industrial manufacturing and sustainable cost optimization.

Frequently Asked Questions

Q: What are the primary applications of Ground Calcium Carbonate (GCC)?

GCC is widely used as a functional filler in the production of rubber, plastics, paints, water-based coatings, papermaking, concrete, and fireproof ceiling materials.

Q: How does GCC help in reducing manufacturing costs?

As a mineral-based filler, GCC can partially replace more expensive resins, polymers, and pigments, lowering the overall cost per unit while maintaining quality.

Q: Can the particle size (mesh) be customized for specific needs?

Yes, we offer a wide range of standard sizes from 100 mesh to 5000 mesh and accept full customization to meet your technical specifications.

Q: Does GCC affect the whiteness of the final plastic or paint product?

No, our GCC is characterized by high whiteness and low refractive index, which actually improves the brightness and opacity of the finished product.

Q: Is Ground Calcium Carbonate stable under high-temperature processing?

Yes, GCC exhibits excellent thermal stability and does not decompose at temperatures below 400℃, making it suitable for extrusion and injection molding.

Q: How does GCC improve the stability of the production line?

Its excellent dispersibility prevents agglomeration and stabilizes melt flow behavior, resulting in fewer defects and more consistent product dimensions.
