Heavy calcium carbonate, according to the thickness, can be divided into several categories: 400 mesh, 800 mesh and 1250 mesh. The actual use of the ratio is about 60: 30: 10. That means, as a heavy calcium carbonate product, the larger amount in plastic industry is 400 mesh. Of course, now the amount of rapid growth is 1250 mesh.
