According to the different production methods of calcium carbonate, calcium carbonate can be divided into Heavy Calcium Carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. White solid, tasteless and odorless. There are two forms of amorphous and crystalline. The crystal type can be divided into orthorhombic crystal system and hexagonal crystal system, which are columnar or diamond-shaped.
Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. The addition of calcium carbonate has a certain effect on improving certain properties of plastic products and expanding their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity. It can also play the following roles:
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve plastic processing performance;
(4) Improve the heat resistance of plastic products;
(5) Improve the astigmatism of plastics;
(6) It can make the product have some special properties;
(7) Reduce the cost of plastic products.
