About this product

Product information from the supplier.

Industrial Light Calcium Carbonate, also known as Precipitated Calcium Carbonate (PCC), is a premium-grade functional filler characterized by high purity, typically exceeding 98% calcium carbonate content. Engineered for versatility, it serves as a critical additive in the production of plastics, rubber, papermaking, coatings, and inks, while also providing essential support for organic synthesis, metallurgy, and glass manufacturing.

With a meticulously controlled particle size ranging from 2 to 3 μm and a high degree of whiteness, our Light Calcium Carbonate enhances the structural integrity and aesthetic finish of end products. By optimizing the balance between mechanical reinforcement and cost-efficiency, it empowers manufacturers to achieve superior rigidity and processing stability in high-demand industrial applications.

Frequently Asked Questions

Q: What is the difference between Light Calcium Carbonate and Heavy Calcium Carbonate?

Light Calcium Carbonate (precipitated) generally has smaller particle sizes and higher purity compared to Heavy Calcium Carbonate (ground), making it more suitable for applications requiring high whiteness and fine dispersion.

Q: How does LCC improve the rigidity of PVC and PP plastics?

LCC particles act as a mechanical reinforcement within the polymer matrix, increasing the stiffness and dimensional stability of the finished product, which is critical for industrial piping and profiles.

Q: Can Light Calcium Carbonate reduce the use of Titanium Dioxide in coatings?

Yes, due to its high whiteness and opacity, LCC can partially replace expensive TiO2 pigments in certain coating formulations while maintaining an acceptable surface appearance.

Q: Which mesh sizes are available for industrial applications?

We commonly supply 100, 325, 600, and 1250 mesh sizes. Customization is also available to meet specific particle size distributions required for specialized rubber or plastic compounds.

Q: How does LCC affect the processing energy of injection molding?

LCC improves the melt flow behavior of the compounds, which can lead to lower extrusion pressures and reduced energy consumption during the molding process.

Q: Is Light Calcium Carbonate chemically stable for long-term use?

Yes, it is chemically inert and highly stable, ensuring that the mechanical properties and durability of the final product are not compromised over time.
