Calcium Carbonate Compound

Calcium Carbonate Compound
Calcium carbonate compound is a mixture of calcium carbonate and base polymers such as polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC). This compound is used as a filler material in various industries to reduce production costs, improve mechanical properties, and enhance the stability of polymer products.
