ColorMatrix™ Amosorb™ SolO2: a recyclable solution Recyclability has become a fundamental requirement for convertors and brand owners. Pressure from the media, the scientific community, end-consumers, and legislation is pushing members of the polymer industry value chain to play their part, in proposing alternative sustainable solutions that can perform in terms of recyclability. Providing solutions that are considered recyclable within the colored bottle stream will thus be an integral part of the recyclability strategy for both convertors and brand owners.

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.
