SABIC FLEX NORYL™ Resin WCA955 Polyphenylene Ether + TPE (PPE+TPE) (Americas)
Categories: Polymer; Thermoplastic; Elastomer, TPE; Polyphenylene Ether/PPO

Material Notes: FLEX NORYL™ WCA955 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 WCA955 resin is intended for evaluation in wire insulation, especially internal wire applications in dark colors. 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 and is also suitable for coating AWG26 and AWG28 copper conductor.

Features: Flexible,Hydrolytic Stability,Low Creep Sensitivity,Flame Retardant,Thin Wall,Non-Halogenated,Non-Chlorinated,Non-Brominated,Good Processability,Ductile
