The role of calcium carbonate filler masterbatch in plastic products
1. Calcium carbonate filling masterbatch can reduce the cost of plastic products, improve production efficiency, and obtain good economic benefits.
2. Calcium carbonate filling masterbatch can enhance the rigidity of plastic products and increase the weight of products.
3. Calcium carbonate filling masterbatch can reduce shrinkage of plastic products and deformation caused by shrinkage.
4. The calcium carbonate filling masterbatch has good dispersibility. It has good solubility with polypropylene and polyethylene. Therefore, even if the amount of filler is larger, the appearance and smoothness of the product can be obtained.
5. The calcium carbonate filling masterbatch has high whiteness and can be flexibly prepared to produce various color products.
6. In the process of processing calcium carbonate filling masterbatch, the use of coupling agent, dispersant and other treatment, can make the calcium carbonate filling masterbatch in the case of large amount of filling, so that products still maintain good mechanical properties.
