OnFlex™-U thermoplastic elastomer compounds are based on thermoplastic polyurethane elastomers (TPE-U). The OnFlex™-U 5400 series are based upon alloys of SEBS and aliphatic TPU, combining the advantages of both raw materials, for example the good processability and soft haptic of a TPE-S with the excellent mechanical properties and abrasion resistance of a TPE-U. OnFlex™-U 5400 compounds are formulated to deliver very good scratch resistance, a wide hardness range, good chemical resistance, and good light stability. Properties are measured using injection molded plaques. Information provided by PolyOne |
