High Impact Calcium Carbonate-Reinforced Polypropylene

Polifil® RMC series compounds are high impact polypropylenes reinforced with fine particle size calcium carbonate. In addition to the highest impact possible, they possess good stiffness, heat aging resistance, solvent resistance, surface quality, and good resistance to environmental stress-cracking. These compounds find applications in...
