POMMERLOCH, Luxembourg – June 17, 2020 – Today, PolyOne announced it is adding production of both post-industrial recycled nylon grades (Nymax™ PIR)  and bio-based thermoplastic elastomers (reSound™ OM) in Europe. reSound™ OM (overmolding) thermoplastic elastomers (TPEs) utilize between 40 and 50 percent bio-renewable content derived from sugarcane, and offer hardness levels and performance comparable to standard TPEs.

SHANGHAI, China – PolyOne today announced that OnFlex™ LO thermoplastic elastomers (TPEs) have received a 2016 China Industry Development and Innovation Award, from Automobile & Parts magazine, an influential industry journal. Consumer concerns and industry regulations have made vehicle interior air quality a major focus for automotive manufacturers,” said Woonkeat Moh, general manager, GLS Thermoplastic Elastomers Asia and Specialty Engineered Materials Asia for PolyOne.
