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. Plastic Crafts

"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.

Modern Dispersions of Leominster, Mass., is highlighting its latest developmental work with nanocarbons to boost the performance of masterbatch concentrates and compound solutions.

Officials said the firm continues to undertake research and development work with new grades of carbon black, graphite and nanocarbons to improve properties such as color, UV resistance and electrical and thermal conductivity.

They added that because of the lower filler loadings required with nanocarbons, better physical properties can be achieved with these types of compounds.

"We've had a lot of interest from OEMs and processors and our ongoing project sampling is promising," Jan Kozma, sales and marketing vice president, said.

One of the developmental grades contains graphene oxide which is being tested to measure property enhancement features including electrical and thermal conductivity, increased tensile strength and improved barrier properties. This grade is targeted for fibers and films.

At K 2022, Modern Dispersions also will showcase its black masterbatches, wood-polymer composites and color concentrates. The company has decades of experience in producing materials that provide UV protection, FDA compliance, high loadings, low-tint performance and customizability.

Kraiburg TPE of Waldkraiburg, Germany, will present new products including Thermolast R recycling compounds. The new materials include compound solutions for the consumer, industrial and automotive markets. They can contain up to 41 percent recycled content.

Thermolast R "combines a lot of things we've been working on for the past 16 months and, in a way, it stands for the transformation [Kraiburg TPE] has undergone for some time now," EMEA Director Monika Hoffmann said.

"The focus is on the fact that, in terms of a sustainable portfolio, we've continuously but surely developed in a transparent, honest way and closely to customers' needs," she added.

Officials added that, in addition to sustainable solutions, Kraiburg TPE also is working on TPEs with added values, such as thermally or electrically conductive TPEs, smooth touch TPEs and high resistance TPEs for cosmetics.
