Audited Supplier | This product is a brand-new polymer-reinforced and toughened nano-calcium carbonate for rubber and plastic. Its formation mechanism lies in: using core-shell theory, through the central atom and the filler itself excellent compatibility (even compatible). Introduce substances with organic ligands into the powder, so that the compounded powder has lipophilicity, lubricity, dispersibility and thermal oxidation resistance in the polymer system; the super coordination ability of metal atoms makes Calcium carbonate products have excellent compatibility and coupling in the polymer system, so that the filling amount of nano-calcium carbonate in the polymer system can be greatly increased, and the special ligand and polymer of nano-calcium carbonate have Entangled with each other, the central atom coupling still has strong reinforcement and toughness for various polymer products after adding nano calcium carbonate products. |
| Performance and usage: |
| 1. On the premise of keeping the original formula unchanged, directly adding 25 parts of NPCC-204 special nano-calcium carbonate can significantly improve the fluidity of the polymer and the excellent processing performance. |
| 2. Add nano-calcium carbonate directly to the product, the toughness of the product, increase the impact resistance of the product, can greatly reduce the cost of the product. |
| 3. Add appropriate amount of nano-calcium carbonate to other polyolefin (PP, PE, PPR, PS, ABS) and other products can significantly improve the tensile and impact strength of the product. |
| 4. It can give the final product extremely strong resistance to yellowing and heat aging. |
