They also add important characteristics, such as SWELLCOAT® water-blocking, water repellence, adhe- sion, color, and wear and UV-resistance to these and many other applications.

On one hand, soft materials can reduce shoulder impact, but it’s tough to find a material that provides plenty of comfort while also resisting material breakdown.

In response to the tests, Avient leveraged its expansive portfolio of specialty additives to tailor the TPE for enhanced UV resistance and to inhibit mold growth—leading to an end product that would perform better for longer.
