SABIC FLEX NORYL™ Resin WCA901 Polyphenylene Ether + TPE (PPE+TPE) (Europe)
Categories: Polymer; Thermoplastic; Elastomer, TPE; Polyphenylene Ether/PPO

Material Notes: FLEX NORYL™ WCA901 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 VW-1 requirements, 105C end use temperature rating, and heat deformation performance as defined by UL 1581. FLEX NORYL WCA901 resin is intended for evaluation in wire and cable applications. It has a Shore A Hardness reading of 91 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
