Cleveland, OH – Avient Corporation announced nine new reSound™ BIO thermoplastic elastomers (TPEs) formulated with bio-renewable content from plants. These new grades contain 35 to 75 percent bio content, validated using ASTM C6866-21 method B.
The new reSound BIO 2800 and 7900 series range in durometer from 30-70 Shore A and offer comparable performance, look, feel, and smell to traditional petroleum-based TPEs. Eight of the new grades can be overmolded on polypropylene (PP) and the ninth grade bonds to both PP and polyethylene (PE). Custom formulations may also be developed to meet specific application or sustainability targets.
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. This makes them ideal for use in consumer goods including personal-care products, cosmetic packaging, toys, or phone accessories.
“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. “These customizable and easy-to-color materials provide customers a way to incorporate more sustainability into their designs, appeal to eco-conscious consumers, and still meet critical functional requirements.”
The new, plant-based reSound BIO formulations are available globally and produced in America and Asia.
reSound BIO formulations are a part of Avient’s broader reSound TPE portfolio, which includes both recycled-content and bio-based formulations.
