AlphaGary Evoprene™ HP 3722 High Performance Thermoplastic Elastomer (discontinued **)
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Styrenic TPE
Material Notes:	Evoprene™ HP is a hydrogenated styrene block copolymer based thermoplastic elastomer. Specially formulated for applications requiring high strength and excellent abrasion resistance, Evoprene™ HP can be used in some applications where thermoplastic polyurethane would normally be specified. Evoprene™ HP has very good, heat ageing properties, excellent hydrolysis resistance and, when properly protected, very good antimicrobial resistance. Can be used in food contact applications with the appropriate stabilizer package Alphagary is part of Orbia.
