FLEX NORYL™ Resin WCD891B

1 of 26 products in this brand
SABIC's Specialties Business FLEX NORYL™ WCD891B 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, 80C end use temperature rating, and heat deformation performance as defined by UL 1581. FLEX NORYL™ WCD891B resin is intended for evaluation in wire and cable applications in dark colors. It has a Shore A Hardness reading of 89 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. This product does not contain PFAS intentionally added during SHPP’s manufacturing process and are not expected to contain unintentional PFAS impurities. Each user is responsible for evaluating the presence of unintentional PFAS impurities.
