High Transparency Calcium Carbonate CaCO3 China Factory and Suppliers
Leading China factory and suppliers of high transparency Calcium Carbonate CaCO3. Our ISO-certified plant provides premium GCC and PCC grades for paint, paper, and plastics, ensuring ultra-high purity and consistent quality.
About this product
Product information from the supplier.
Our High Transparency Calcium Carbonate (CaCO3) is a premium industrial mineral engineered for superior clarity, purity, and performance. Sourced from high-quality natural calcite and produced through advanced mechanical and chemical processes, our product is available in both Ground Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC) grades to meet the exacting standards of the global paint, paper, and plastics industries.
Designed to optimize material properties, our calcium carbonate acts as a high-efficiency filler and improver. By leveraging ultra-fine particle size distributions (from 7µm to 2000+ mesh), it enhances the texture, opacity, and structural integrity of end products while significantly reducing production costs. Whether you require uncoated fine powders or specialized coated versions, our ISO-certified manufacturing ensures consistent whiteness and chemical stability.

Frequently Asked Questions
Heavy calcium (GCC) is produced by crushing natural calcite and is generally more cost-effective. Light calcium (PCC) is synthetically produced, offering finer particle sizes, higher oil absorption, and better stability in emulsions.
It acts as a filler and pigment that enhances texture, opacity, and finish. It also improves the paint's resistance to weathering and abrasion while ensuring a smooth application.
Yes, it is widely used to reinforce plastics, increasing their strength, rigidity, and durability, especially in packaging and automotive parts where clarity is essential.
Our products typically maintain a CaCO3 content of ≥ 98.5%, with very low levels of iron, manganese, and aluminum to ensure maximum whiteness and transparency.
Yes, we offer a range from ultra-fine powders (7µm) to coarser grades (over 2000 mesh), including both coated and uncoated options to suit your specific application.
Our factories are ISO certified, and our production techniques are backed by 23 national patents, ensuring global quality compliance.
