This product is a fine precipitated calcium carbonate with its fine and uniform particles,special surface activity as well,it can facilitate the mould release,improve the processability of products,enhance the surface finish and the flexing resistance,increase the quantity of filler and thus reduce the production cost.
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
