Ground Calcium Carbonate (GCC) & Wet Grounded Calcium Carbonate (CaCO3)



The superfine specially ground calcium carbonate & coated calcium carbonate for plastic are functionality fillers that our company specializes in research and development according to the characteristics and performance of the process of the plastics industry. They choose high purity and high whiteness calcite as raw material.

NAT process is that advanced technology through which these Calcium Carbonate & Coated Calcium carbonates are produced and we compound the process of drying in a static station and constant temperature for multiple sections and secondary depolymerization. And after grinding in surface polishing treatment and multiple sections. Particle size distributes narrowly and shape is similar to the spherical shape. Which does not abrade equipment and inner oil absorption, can absorb other no unnecessary additives in the plastic process reduce. These heavy calcium carbonates are made of high purity and high whiteness calcite as raw material, so there is no toxin and taste and will not affect other additives. These calcium carbonate use large-scale slurry pool, and are treated in the equably, so the quality is stable, they are compatible with resin very well after the surface is activated treatment.

Natural calcium carbonate for paint, Rubber, Plastic, textile aids, and building material

Natural ground calcium carbonate is used for paint, Rubber, Plastic, textile aids and building material this natural calcium carbonate Select high purity and high whiteness calcite as raw material. It is produced by domestic advanced gravel and imported separation equipment.

This natural ground calcium carbonate Select high purity and high whiteness calcite as raw material. It is produced by domestic advanced gravel and imported separation equipment. Our soil calcium carbonate series are characteristic of uniform particle size, constant color, and good dispersity. Heavy calcium carbonate is a universality filler.

Calcite Mineral for Plastics

1. Better flow and strenght in PVC Pipe
2. Better loading in PVC Compounding and master batches.
3. Low choking due to fine particle size.
4. Increased output due to uniform coating.

High Opacity Calcite for Paints

We offer calcite powder, which provide a greater covering strength, thus increasing the performance of high opacity paints, oil synthetic and other coatings. The excellent whiteness of our carbonates avoid interference with the paints colors and contribute to their opacity and that the paint will cover, without dripping, the surfaces.


They are widely used in paper making, plastic, rubber, paint, and building materials etc.
