Usage:

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

polyethylene (PE), polypropylene (PP), ABS, etc.

Characteristic:

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 high polymer 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 compatibility
