FLEX NORYL WCP761 resin is a high flow, flexible, non-reinforced injection moldable blend of Polyphenylene Ether (PPE) + Thermoplastic Elastomer (TPE). This material contains non-halogenated flame retardant and carries a UL94 flame rating of V0 at 6mm. FLEX NORYL WCP761 resin is intended for evaluation in over-molding applications such as plugs, strain reliefs, and connectors. It has a Shore A Hardness reading of 78 and exhibits low specific gravity, very low water absorption, and dimensional stability.
