CaCO3:
    Industrial precipitated calcium carbonate (CaCO3)
    Molecular Formula ：CaCO3
    Molecular Weight：100.09
    Appearance：White powder 
  PCC uses
    Widely used in rubber, plastics, PVC pipe, steel products, paint, paper, paint, sealants, household goods, medicine, feed as fillers and reinforcing agents. This would increase the volume and lower costs, the main thing is to improve the processing performance of the matrix, but can accessory, tensile, wear resistance, tear resistance, such as raising shiny effect, and there is not a general calcium carbonate filler, but is called a functional filler.
    CaCO3 white, good mobility, PVC tubes, profiles the largest filler, played a pair of products to increase volume, stable size, heat, formation, etc. sheen obviously, thereby lowering the cost, quality products to achieve the objective.
    Calcium rubber, oil absorption value is low, reinforcing effects, good wear resistance and the strong tear-resistant characteristics.
    Coating of calcium can increase adhesion, solid colors antioxidant, increasing fill volume, lower cost advantages
