Lihat Profil SellerHigh-Clarity, Food-Safe PP with Medium Flow & Enhanced Crystallization for Transparent Molded Parts
PP PR311 is a premium-grade random copolymer polypropylene engineered for injection molding applications requiring high optical clarity and mechanical durability. Enhanced with a nucleating agent, it offers accelerated crystallization for faster cycle times and reduced haze (9%) for superior transparency. With balanced stiffness (1000 MPa flexural modulus) and impact resistance (8.3 kJ/m²), PR311 is ideal for food-contact packaging, caps, closures, and consumer goods. Its organoleptic neutrality ensures no taste or odor transfer, meeting strict food safety standards. Easy to process at 190–240°C melt temperature and backed by consistent quality control.
