In order to deliver the best blow molding performance, it is customary within the conversion industry to establish ‘recipe’ guidelines per resin/per supplier as different PET resin production technologies and different specific resin formulations can significantly influence the blow molding performance. As a major supplier of additives and colors to the plastics industry, ColorMatrix has, in the course of supporting its customers worldwide, developed best practice guidelines for its products which it provides as a free service. Such advice, for example how to set up blow molding machines, is not equipment specific and therefore ColorMatrix would always recommend using local or expert technicians in addition to following best practice points listed below; • Preforms should be conditioned for minimum 24 hours prior to blowing • Preforms should always be used in a FIFO manner (First In, First Out) • Octabins of preforms should be segregated and blown per resin type, i.e. not mixed with other resins • A preform traceability system should be in place such that any process upsets can be quickly followed up and corrected • Enhanced QC preform checking resources for bottle distribution, aesthetics and integrity should be on-hand during the performance optimization trials • Prior to any process optimization, the blowing machine performance should be verified as being within normal i.e. accepted standard ranges and all important components and control features are working satisfactorily.

Rigid thermoplastics include both commodity thermoplastics and engineering thermoplastics, such as polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS), polycarbonate (PC), acrynitrile-butadiene-styrene (ABS), poly(ethylene terephthalate) (PET), poly(methylmethacrylate) (PMMA), styrene acrylonitrile (SAN), poly(phenylene oxide) (PPO), polyamide (PA), PC/ABS blend and PPO/PS blend etc.. Thus, one of the limitations for most of the existing TPE overmolding technology is that one needs to develop and use different TPE materials for different substrates. Novel TPE materials that can overmold onto various engineering plastics also were reported elsewhere (2-4).

It’s in this spirit that we joined legacy PolyOne and the Clariant Masterbatch business, two complementary businesses, and formed a new one that we’ve named Avient. As one, we are better positioned than ever before to lead and to make a positive difference. Our exceptional polymer scientists and design engineers are integral to their product development process.
