8000 mesh water-ground calcium carbonate

8000 mesh water-ground calcium carbonate
1. Application field:
Plastic products industry, mainly used for rigid PVC, UPVC pipes, polyethylene (HDPE/LDPE), polypropylene (PP), ABS, ACR, polyethylene (CPE) and other resins.

2. Features:
As a functional filling material for plastic products, compared with physical grinding of ordinary calcium carbonate, this product uses membrane dispersion microstructure method for chemical synthesis, with the advantages of small particle size (30-60nm) and large specific surface area. HDPE is modified with nano-calcium carbonate. When the mass fraction of nanoparticles reaches 4%-6%, the impact strength of the composite material is greatly improved compared with pure HDPE, and the yield strength and modulus are also improved.

3. Quality indicators:
