Applications: fillers of paint, print ink, plastic, rubber, adhesives, pharmacy, fodder,
paper-making, polyvinyl chloride (PVC), polyethylene (PE), polypropylene(PP), ABS,
building materials
Features:
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
