Light Calcium Carbonate

Light Calcium Carbonate, also named precipitated calcium carbonate, is a kind of active 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
