MATERIAL REDUCES COSTS WITH LOWER SPECIFIC GRAVITY, AND HIGHER FLOW THAN COMPETITIVE TPV © 2021, All Rights Reserved Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012 To learn more about Versalloy™ Thermoplastic Vulcanizate, contact Avient at +1.844.4AVIENT (1.844.428.4368) or visit avient.com. The hose manufacturer decided to explore other material options that would meet requirements such as excellent colorability, good surface appearance, high flow for optimal productivity, and of course, compliance with U.S. In addition to its excellent colorability and high flow, the Versalloy solution possessed a lower specific gravity and resulted in lower scrap rates compared to the competitive TPV, providing the opportunity to reduce system costs.
