Used in rubber

can increase the volume of the rubber, to improve the rubber processability, half reinforcing or reinforcing
effect, and can adjust the hardness of rubber.

Used in plastic

Plastic industry is one of the largest consumption of heavy calcium carbonate, refining the coarse whiting powder, can obviously increase the plastic composites strong strength and mechanical properties of the interface. Plastic is used in fine coarse whiting powder, can reduce the manufacturing cost, but also improve and change its properties.

Used in papermaking

Papermaking industry with heavy calcium carbonate is mainly used for two purposes, one is for packing, 2 it is the coating. At present, our country papermaking process in most paper mills are using the acid method, using packing mainly kaolin and talcum powder, coarse whiting will replace acid type sizing, coarse whiting powder as the filler will replace the talcum powder in large range or high soil.

- Packing: 25KG/PP PE BAG, 25KG/VALVE BAG, 1MT/jumbo bag, or as required.

- the delivery term may be FOB, or CNF, and CIF.

- Port: Haiphong Port
- Lead Time : Shipped in 20 days after payment

eavy calcium carbonate, also called ground calcium carbonate, is produced by natural superior calcite, which has high purity and whiteness. The size ranges from under 400 mesh which is called primary products, to 2000 mesh or above, depending on your requirement.
Heavy (Ground) Calcium Carbonate is widely used as filler and improver in plastic, paint, paper-making, rubber, pharmacy, feed,daily chemical, ceramics, adhesives and ink industry. Factory calcium carbonate powder caco3 calcium carbonate price
