SABIC FLEX NORYL™ Resin WCD933 Polyphenylene Ether + TPE (PPE+TPE) (Americas)
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Polyphenylene Ether/PPO
Material Notes:	FLEX NORYL™ WCD933 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. FLEX NORYL WCD795 resin is intended for evaluation in AC cable insulation applications such as HD 21.14 flexible cables. It has a Shore A Hardness reading of 93 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
