    6.advantage:

    1)      Identical grain size,low oil absorption value

    2)      To reduce the cost of products;to make products have good foamed effect

    3)      To enhance hardness,rigidity,size ,stability,fire-retardantness,glossiness of products

    4)      Calcium carbonate is used for highpolymer material to improve the craftwork of processing and enhance the mechanics and hot stability of products;It can reduce the cost with the enhancement of dispersibility and compatibilitythe relative product:

     vermiculite,color sand exc.

    7.sample:free

    8.Main application:

    Fillers of plastic such as for plastic,rubber,paper,polyvinyl chloride(PVC).
