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