Avient’s ColorForward™ Color Trend Forecasting Tool for the Plastics Industry Forecasts an Eclectic Color Palette in 2026  The result is a set of twenty color aesthetics that aim to guide and inspire designers and marketers in their color selections for new polymer applications. Carnival of Fuels examines humankind’s quest for alternative energy sources to meet the increasing power needs driven by the growing electrification of our world and a surge in data centers.

These reSound BIO TPEs have an opaque natural color and offer excellent colorability, just like prime TPEs. This tone allows the materials to showcase a natural aesthetic or be colored to match design specifications with traditional TPE colorants or sustainable color options from Avient. Brand owners continue to seek ways to be more environmentally responsible and these new bio-polymers were developed to help them achieve those goals,” said Matt Mitchell, director, global marketing, Specialty Engineered Materials at Avient.
