Ultra-Fine and High-Performance for Advanced Applications
We offer Fine Calcite Powder. This product reflects our pursuit of "ultra-fineness" and "high performance." We use natural high-purity calcite as the raw material. It is processed through dry grinding or wet grinding combined with precision classification technology.
Our factory has six automated production lines with an annual capacity of 300,000 tons. Our team consists of 30 skilled employees, including over 12 technical staff. We are not just a supplier-we are a partner in improving the performance of your composite materials. Our Fine Calcite Powder is a high-performance product.
Key Specifications and Superior Quality
We maintain strict quality control throughout the entire process, ensuring stable chemical composition and excellent physical properties. The table below lists our key specifications.
The calcium carbonate content ranges from 95.0% to 98.0%. The whiteness ranges from 80% to 96%. The fineness is adjustable from 200 mesh to 1250 mesh, with a median particle size (D50) of 5μm to 15μm. Our Fine Calcite Powder is designed for demanding applications.

Wide Applications and Simple Process
Our Fine Calcite Powder is widely used across many industries. It is used in plastics for PVC pipes, profiles, and cable materials. It is used in coatings for interior and exterior paints as well as industrial primers. It is used in rubber products such as tires and seals, and also in inks, paper, and artificial stone.
We conduct particle size testing on every batch to ensure consistent fineness. With a monthly capacity of 300,000 tons, we can ship standard orders within 3–5 working days after receiving the deposit.
