Precipitated calcium carbonate is an inorganic compound mainly contained in limestone and calcite. Precipitated calcium carbonate generally made from natural mineral powder, according to different processing methods.
We supply OREWORLDMT Precipitated calcium carbonate for rubber, plastics, paints and paper industries, the products are exported to South Korea, India, Russia, Bangladesh, Malaysia, Philippines, Hong Kong and other regions.
OREWORLDMT Precipitated calcium carbonate Type A For Rubber
Our Precipitated calcium carbonate is widely used in rubber industry, often fill in tires, rubber hose, adhesive tape, seals, auto parts and other rubber products. Filling a large number of Calcium Carbonate in the rubber or synthetic rubber, can increase the volume of the rubber products, save costly natural rubber or synthetic rubber, reduce costs.
Our OREWORLDMT Precipitated calcium carbonate make the rubber easier for mixing, decompose, processing, and cast, vulcanized rubber surface is smooth, elongation large, high tensile strength, small deformation, high bending strength, strong tear-resistant.

OREWORLDMT Precipitated calcium carbonate Type B For Plastic
Precipitated calcium carbonate as an inorganic filler used in plastics for many years. Our OREWORLDMT Precipitated calcium carbonate can increase the volume of plastic products, reduce costs, increase hardness and rigidity, reduce plastic shrinkage ratio and improve dimensional stability; improve the processing properties, increase heat resistance, improve plastic astigmatism, anti - abrasions nature of smoothness; at the same time, can increase impact strength in gaps and mixing performance.
