Polifil® C

Polifil C

Calcium Carbonate-Reinforced Polypropylene

Polifil® C series compounds are homopolymer polypropylene resins reinforced with fine particle size calcium carbonate. They combine high impact with stiffness, good colorability, resistance to environmental stress-cracking, good surface, and low mold shrinkage. Polifil® C products in the 20 to 40% range are UL94 HB rated. These compounds are used in appliances, electrical components, housewares, toys, automotive, and utility products. Standard processing techniques are applicable. Use this information as a guide to aid you in selecting the proper resin for your application. TPG will custom compound and fine-tune our formulations for your application.
