The latest addition to the OnFlex line of TPEs from PolyOne Corp., Avon Lake, Ohio, is designed to improve driver and passenger safety and comfort. This OnFlex LO TPE technology is said to significantly reduce VOCs and to minimize both fogging and odor in interior automotive components.

A broad range of applications are cited as well suited to OnFlex LO, including HVAC seals, buttons, controls, coin trays and drink holder mats. The material can be overmolded onto polyolefin substrates using two-shot injection molding. PolyOne tested OnFlex LO TPE against its existing TPEs according to VDA 278 standard for VOCs and fog, and VDA 270 standard for odor. Results showed the new TPE cut VOC emissions by about 50% and fog emissions by 40%, while maintaining outstanding low-odor performance.
