Calcium carbonate (CaCO3) powder is a natural mineral that’s used in calcium carbonate masterbatch production. Calcium carbonate masterbatch is a filler that’s made of calcium carbonate, base resins, and various plastic additives. It’s often used in the plastic industry as a cost-effective solution that can improve the properties of finished plastic products. Calcium carbonate powder is most compatible with polyolefin (PP, PE) resins, but it can also be mixed with other common resins like PS, ABS, PVC, and EPS. The exact proportion of calcium carbonate to resin used in each production depends on the specific requirements. For example, calcium carbonate mixed with PP masterbatch is often used in the injection molding method to produce household appliances like furniture, containers, and bottles.
