Application:

1.  In rubber manufacture: Calcium carbonate was the earliest filler used in the rubber industry. It can enlarge the capacity in the rubber products, forsaving the cost. It also enhances the tensile strength, abrasion and tearingstrength.

2.  Plastic manufacture: As the framework in plastic products, keeping stability of the products, strengthen the products, keening surface smoothly, since the calcium carbonate is high white, it can place the expensive the white polyethylene, for whitening the plastic products.

3. In the coating: calcium carbonate can be used as white pigment, up a frame function, calcium carbonate in the coating industry can be used as inert pigment. Due to the calcium carbonate color is white, in coating relative latex, solvent prices are cheap, and fine grain, can in coating evenly dispersed, so is a lot of use of inert pigment. Calcium carbonate filling can enhance primer to basic level surface sedimentary and permeability.

3.  Paper making: Whitening the paper, and as the filler, can reducing the pulp, for saving the cost

Storage and Transport: It should be stored in a dry and ventilative warehouse. Avoid rain and moisture during transport. Furthermore, it should be stored separately from poisonous substance.
