Pinnacle 5135C3 and 5155C3 resins

Using Millad NX8000 clarifiers from Milliken Chemical (which are said to provide a fourfold improvement in yellowness index and can be molded at lower temperatures), this firm now offers several new polypropylene polymer grades that provide peak brightness and improved aesthetics compared to existing offerings. The two new PP3 random copolymer grades enable the production of housewares and other products with a brighter and cleaner look. The Pinnacle 5135C3 and 5155C3 resins enable shorter cooling times and a broader processing window, which can provide cycle-time reductions of up to 26%. Lower molding temperatures can reduce energy consumption by up to 22%. The PP3 resins achieve a yellowness index rating of –15, which compares favorably to the –2.5 level typical of standard clarified polypropylene.
