These bio-derived and glass fiber-reinforced formulations utilize 16–47% natural filler from renewable plant sources, including corn, straw, and wheat. The Nymax BIO portfolio includes six grades that offer lower warpage plus excellent surface appearance and colorability compared with traditional PA66 glass fiber-filled materials. KEY CHARACTERISTICS • Bio-polymers that reduce the carbon footprint value significantly • Achieves equivalent performance as PA66 glass fiber-filled materials • Excellent surface appearance and colorability • Lower warpage compared with PA66 glass fiber-filled materials • Cost-effective alternative to PA66 glass fiber-filled materials • Excellent dimensional stability and property retention rate after water uptake • Commercially available in Asia APPLICATIONS Nymax BIO formulations can be applied to reach sustainability goals in demanding applications including: • Transportation • Consumer goods • Industrial • Building and construction PRODUCT BULLETIN 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.

These constraints are fostering higher prices, longer lead times, and increased interest in silicone alternatives such as thermoplastic elastomer (TPE) tubing solutions. We’re excited to add the new Versaflex grade to our expanding set of solutions that enable customers to continue pursuing product innovation and meet market demands,” said Jim Mattey, global marketing director, Specialty Engineered Materials at PolyOne.

MANNHEIM, Germany – PolyOne unveiled new OnFlex™ LO thermoplastic elastomers (TPE) today at the VDI Plastics in Automotive Engineering Conference (Stand 83A). While our existing TPEs lead the industry in low emissions performance, we continue to innovate and anticipate future demands and stricter requirements.
