What is calcium carbonate masterbatch? What benefits do it bring to the plastic industry?

Calcium carbonate masterbatch is a combination of limestone powder (CaCO3 on primary tar) and other additives, the materials are mixed together during the heating process to form plastic lines and are extended into fibers, after that it will be cooled and cut into small particles. The calcium carbonate masterbatch product will be applied continuously in production processes such as injection molding, film blowing, laminating, spinning, etc.

Calcium carbonate masterbatch helps reduce the cost of production for the final plastic products, because the ingredients can replace part of the primary tar in the process of manufacturing into the final plastic product. In addition, the filler masterbatch also helps increase the quality of plastic products, improve production conditions as well as increase the mechanical properties of products such as increasing hardness, reducing shrinkage, …

What applications do calcium carbonate masterbatch have in producing plastic products?

In order to produce calcium carbonate masterbatch by PE/ PP, people often use from 70% to 80% limestone powder in processing of blowing film, blowing mold to produce plastic products such as plastic baskets, vegetable containers, plastic prices , plastic pipes, woven bags ... have a smooth surface, good gloss and durability. Especially some products from PE is the base ingredient that has the final products such as bags in supermarkets, agricultural plants protection film from external agents such as insects, heavy rain, ...; membrane used in greenhouses, garbage bags, film wrap food, cans, bottles, jars …

With 70% talc powder to produce calcium carbonate masterbatch that the final products like adhesive tape or woven bags, nets, ... will have certain transparency and no color change for a long time, maintain durability and rigidity.
