FLEX NORYL WCD883CU resin is a flexible, non-reinforced extrudable blend of Polyphenylene Ether (PPE) + Thermoplastic Elastomer (TPE). This UV stabilized material contains non-halogenated flame retardant and performance capable of meeting EN 50265-2-1 requirements. FLEX NORYL WCD883CU resin was developed for evaluation in AC cable jacket applications such as HD 21.14 flexible cables that require EU VDE and light color. It has a Shore A Hardness reading of 88 and exhibits superior thermal stability, very low water absorption, good electric properties, and low specific gravity. Processing is typically conducted on standard extrusion equipment, and UL 1581 testing is conducted on 2.0mm wire with 0.12mm X 20 stranded copper conductor.
