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. Consisting of four overmolding grades compatible with rigid polypropylene and one suited to ABS, all grades are formulated for durability, property retention, and UV resistance comparable to traditional TPEs.

SHANGHAI – February 25, 2021– Avient Corporation, a premier provider of specialized and sustainable material solutions and services, today launched its Versaflex™ CE 3130 series – engineered thermoplastic elastomers (TPEs) to overcome the challenge of surface blooms on overmolded consumer electronics and boost productivity. Blooming or efflorescence can prematurely spoil a premium, overmolded TPE surface on consumer electronics devices. These TPEs also offer critical UV and stain resistance to endure everyday wear and tear.
