SABIC FLEX NORYL™ Resin WCD944 Polyphenylene Ether + TPE (PPE+TPE)
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Polyphenylene Ether/PPO
Material Notes:	FLEX NORYL™ WCD944 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 EN 50265-2-1 requirement and is IEC 60754 compliant. FLEX NORYL WCD944 resin is intended for evaluation in wire and cable applications such as optical fiber cable jacketing. It has a Shore A Hardness reading of 95 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. Features: Flexible,Hydrolytic Stability,Low Creep Sensitivity,Flame Retardant,Thin Wall,Non-Halogenated,Non-Chlorinated,Non-Brominated,Good Processability,Ductile Information provided by SABIC
