Lightweight Calcium Carbonate
Lightweight calcium carbonate is also commonly called Precipitated Calcium Carbonate (PCC).It is chemically the same compound as Calcium Carbonate, but its particle size, shape, and density are controlled during manufacturing.Light Calcium Carbonate
Characteristics
* The particle size is smaller than that of heavy calcium carbonate; Better fineness.
* Better whiteness.
* Less impurities; high purity.
* The appearance is mainly spindle or spherical shape.
* Good dispersion
Lightweight Calcium Carbonate Main Applications
Lightweight calcium carbonate has a wide range of functions and can be used in the following industries:
The rubber industry: calcium carbonate is one of the earliest largest filling agents used in the rubber industry.
Plastics industry: calcium carbonate play a great role in the stability of plastic products, improve the hardness of the products, and improve the surface gloss and surface smoothness of the products.
Paint industry
Water-based coatings industry
