Calcium Carbonate Filled Homopolymer

Calcium carbonate filled polypropylene compounds offer improved stiffness versus unfilled materials. They offer substantial improvements in drop weight (Gardner) impact over both unfilled polypropylene and other types of filled polypropylene. Calcium Carbonate also offers advantages in appearance, gloss, and colorability due to its bright white color.
