WEB EXCLUSIVE: Two new polypropylene random copolymers are said to give housewares and other products a dramatically brighter and cleaner look, thanks to Millad NX8000 clarifier from Milliken Chemical, Spartanburg, S.C. New PP3 grades from Pinnacle Polymers LLC, also of Spartanburg, achieve a very low yellowness index of -15, compared with the -2.5 typical of clarified PP. The new grades also reportedly offer up to 26% shorter cycles and ability to mold at up to 22% lower temperatures than standard PP.
The two new grades, both FDA approved for food contact, are Pinnacle 5155C3 (55 MFR) and 5135C3 (35 MFR). They are made by the Unipol process.
