Compounders show off ways to improve resins at K

Compounders including Avient Corp., Modern Dispersions Inc. and Kraiburg TPE will be at K 2022 with many new ways to improve resins.

New products offered by Avient of Avon Lake, Ohio, include Cesa Nox-brand polyolefin antioxidants for recycling. Officials said these sustainable materials are designed to improve the customer experience of working with post-consumer (PCR) content for materials used in packaging.

"Avient is fully committed to increasing opportunities to expand the use of recycled polymers, addressing any barriers that arise either during the recycling process or when customers want to incorporate PCR content into existing or new applications," said Norbert Merklein, vice president of the Europe, Middle East and Africa regions of Avient's Color, Additives & Inks unit.

The new additives are based on a special formulation that protects post-consumer polyolefins against oxidation, which can lead to defects like black spots, gels and discoloration. The antioxidant can be added to post-consumer resin early in the recycling process or incorporated in virgin resin to prepare it for future recycling.

Avient also has added two new grades of reSound REC-brand thermoplastic elastomers (TPEs). Both grades are formulated with polyvinyl butyral (PVB) recycled from automotive glass by Shark Solutions of Denmark. Also announced are two new Edgetek PKE-brand polyketone grades with non-halogen flame retardants.

Applications for reSound REC TPEs include automotive exterior and under-hood components, while Edgetek PKE NHFR formulations are designed for electric vehicle components, including connectors.

"We are closing the loop by incorporating recycled PVB from vehicle glass into our reSound REC TPEs, which then go back into other automotive applications, as well as consumer products including grips and handles for personal care items," Matt Mitchell, specialty engineered materials global marketing director, said.

He added that with Edgetek polyketone grades, Avient offers alternatives to nylon that can lower carbon footprints.
