Calcium carbonate is widely used in daily chemical industry as fillings in artificial bricks, rubber, plastic, papermaking, coating, paint, printing ink, electric cable, food, medicine, spinning and weaving ,fodder and tooth paste, etc. lt can help to increase the volume of products and reduce costs.
1,In rubber , it can reduce the amount of expensive natural rubber, increase its volume ,reduce costs, After adding calcium carbonate then can obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate
2,In painting/coating ,it is as filling and as framework, latex paint more than 30% amount are used in thick paint, 26%-60% amount are used in water-based coating. It is not easy to  make the coating  deposition , easily dispersed ,good glossness.
3,In plastic, it can increase the volume of plastics,reduce costs,improve size, stability, hardness and tencity of plastic products.It can also improve the processing properties, heat resistance and astigmatism.

In plastic woven bags of 25kg net each, 40 bags per pallet, 20T per 20GP.
We can do packaging 500kg or 1000kg per bag if you demand.
Note: stored in a dry and clean storage.
