PolyMirae Moplen RP344NK Injection Molding Grade Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Molded

Material Notes: Moplen RP344NK is a nucleated polypropylene random copolymer manufactured by PolyMirae using Spheripol process technology licensed from LyondellBasell. Moplen RP344NK is specially designed for good processability, excellent clarity, and good hinge property in low processing temperature with balanced mechanical properties. Moplen RP344NK is a random copolymer particularly suitable for injection molding of transparency container, houseware, food container, bottles(IBM/ISBM), caps and lids. Moplen RP344NK meets the FDA requirement in the code of Federal Regulations in 21 CFR 177.1520 for food contact.

Product Features: Good processability and excellent clarity in low processing temperature/High productivity with shorter cycle time than conventional random PP/Good hinge property/Less bubbles(Voids) in final products/High gloss/Good mechanical property balance/Low odor and low taste transfer

Typical Applications: Transparency container, Houseware, Food container, Bottles(IBM/ISBM), Caps and lids, etc
