reSound™ REC TPEs: specially developed for automotive interiors, formulated with 55% post-consumer recycled (PCR) content to offer a more sustainable alternative to standard TPE grades without compromising performance criteria such as ultraviolet (UV) stability, low volatile organic compound (VOC) content, low odor, and low fogging in applications such as heating, ventilation, and air conditioning (HVAC) nozzles, interior mats, and cup holders

OnFlex™ TPEs: offer high thermal, chemical, and mechanical property profiles with low odor for demanding applications in transportation, including OnFlex AF 7210-70 for automotive components with low volatile organic compounds (VOCs), low fog, and lower density compared to previous material grades, plus excellent low-gloss surface finish and soft touch for high-quality aesthetics

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. We are better together through: Keeping Safety First — PolyOne and Clariant are both ACC Responsible Care® companies, and nothing is more important than the health, safety and well-being of our people. Leading in Sustainability — PolyOne and Clariant are both founding members of the Alliance to End Plastic Waste, and we are committed to meeting the needs of the present without compromising the ability of future generations to do the same.

Overmolding TPE compounds have a relatively low viscosity. GLS has focused its R&D efforts on the chemistry and technology of developing overmolding compounds to virtually any substrate.

Natural, light-colored or clear formulations will more easily show contamination or discoloration. For clear TPEs, parts that have been processed at too low a temperature will have a frosty surface appearance. Most of the GLS soft TPEs are either water-clear or translucent.
