Light Calcium Carbonate

Light Calcium Carbonate

Light Calcium Carbonate also named precipitated calcium carbonate. The manufactured process of light calcium carbonate is achieved by chemical synthesis. Because its settlement volume (2.4-2.8mL/g) is larger than that of the heavy calcium carbonate produced by mechanical method (1.1-1.9mL/g), it is called light calcium carbonate.

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

Light Calcium Carbonate Main Applications

Light calcium carbonate has a wide range of functions and can be used in the following industries:
1)The rubber industry: calcium carbonate is one of the earliest largest filling agents used in the rubber industry.
2)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.
3)Paint industry
4)Water-based coatings industry
