THE SOLUTION Working with Plastic Bank, Avient expedited its approval as a new supplier, reducing Hager’s project timeline. Avient is pleased to have been part of the collaboration between Plastic Bank and Hager Group, helping one of its recognized customers move towardsreaching its sustainability goals by transforming discarded ocean-bound plastic into high-performance polymers.

ColorMatrix™ Optica™ Global PRT Toner Dispersions Handling and Usage ColorMatrix Optica Global PRT Red and Blue dispersion toners are intended for use primarily in PET bottle polymer production processes and, although they are suitable for all polyester manufacturing processes, are used successfully throughout the world on all types of PET production technologies. The use of heat in an attempt to drive the toner into solution will result in a dispersion which is in a state of super saturation.

GLS™ TPE AUTOMOTIVE SOLUTIONS ENABLE LONG-TERM PERFORMANCE WITH TPEs FOR FASTENERS AND CLIPS The average length of vehicle ownership is on the rise, placing greater demands on all elastomeric materials to maintain long-term sealing performance in fasteners and clips.

PolyOne’s industry-leading portfolio of engineered composite panels offers a solution to these challenges. Our composite panels are custom engineered by varying core thicknesses to increase or decrease stiffness; by varying core materials (including end-grain balsa, foam or engineered woods) to increase or decrease weight; by varying fiber to modify the stiffness-to-weight ratio; and by varying the base polymer to increase or decrease strength

LubriOne™ Internally Lubricated Formulations – PTFE-free Solutions LubriOne™ Internally Lubricated Formulations are self-lubricating polymers, offering low coefficients of friction (COF) and improved wear-resistance properties for molded parts.

VALUE SOLUTION Traditionally light blocking was achieved with use of multilayer HDPE and PET packaging. Both paperboard and multilayer polymers restrict design freedom, so that the packaging is often less than ergonomic.
