Homepage // News Center // Sustainable TPEs from Avient Featured at SPE TPO Conference During the conference, Christopher Engel, advanced research & development engineer at Avient, will be giving a presentation on exploring bio-based thermoplastic elastomers (TPEs) in automotive applications. Made from renewable sources, materials like reSound™ BIO formulations help reduce carbon footprint and can perform like traditional TPEs.

Homepage // News Center // PolyOne Launches Specialty Automotive TPEs and Design Services in Europe This includes the launch of OnFlex™ LO thermoplastic elastomers (TPEs), featuring reduced levels of volatile organic compounds (VOCs) for vehicle interiors, and the availability of its IQ Design Labs service in Europe. PolyOne also introduced OnFlex LO specialty TPEs, which help automotive OEMs improve the driver experience by reducing the number of VOCs in vehicle interiors by up to 50 percent.

Since our highly successful TPE acquisition of GLS in 2008, we've continually invested in, globalized and grown in TPE innovation and its broad value-added uses," said Swanson , Director, Investor Relations, PolyOne Corporation, +1 440-930-1018, eric.swanson@avient.com; Media Contact: Kyle G.

Top 10 Rules for Overmolded Components 1. .Match the chemistry of the TPE to the substrate for optimized bonding 2. .For new component designs, flow ratios (L/T) should be between 80:1 – 120:1 3. .Incorporate air vents between 0.0005" and 0.001" along the perimeter and/or at the end of fill 4. .Incorporate good flow shutoffs to prevent flashing 5. .Add surface texture to prevent sticking and to mask aesthetic defects 6. .Use a rigid substrate for easy ejection from the mold 7. .Ensure the TPE layer is thick enough to ensure good bonding.
