FLEX NORYL™ Resin WCD855

FLEX NORYL WCD855 resin is a flexible, non-reinforced extrudable blend of Polyphenylene Ether (PPE) + Thermoplastic Elastomer (TPE). This material contains non-halogenated flame retardant and performance capable of meeting UL 1581 VW-1 requirements. FLEX NORYL WCD855 resin is intended for evaluation in AC cable jacket applications that require UL62 at 90C or 105C temperature rating and black color. It has a Shore A Hardness reading of 85 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
