Avient OnFlex™ S EF 80A-3S1977 Thermoplastic Elastomer (TPE)
Categories:	Polymer; Thermoplastic; Elastomer, TPE
Material Notes:	OnFlex™-S EF thermoplastic elastomer compounds are based on hydrogenated styrenic block copolymers. This range of compounds are formulated to deliver good mechanical properties together with excellent processability, in addition to typical OnFlex™-S properties such as a wide hardness range, low compression set, good colourability and a wide temperature operating range. OnFlex™-S EF compounds are semi-filled, making them opaque and with a medium density. Properties are measured using injection molded plaques. Information provided by PolyOne
