FLEX NORYL™ Resin WCP921

1 of 26 products in this brand
SABIC's Specialties Business FLEX NORYL™™ Resin WCP921 is a high-flow, flexible, non-reinforced injection-moldable blend of polyphenylene ether (PPE) and styrene ethylene butylene styrene (SEBS) with polyolefin. It contains non-halogenated flame retardant and has a UL94 flame rating of V0 at 6mm. This material is intended for evaluation in over-molding applications such as plugs, strain reliefs, and connectors and has a Shore A hardness reading of 88 as well as low specific gravity, very low water absorption, and dimensional stability. 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.

Note
  • ᵍ Measurements made from Laboratory test Coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
  • ʳ UL Ratings shown on the technical datasheet might not cover the full range of thicknesses, colors and regions. For details, please see the UL Yellow Card.
  • ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
  • ¹¹ The information stated on Technical Datasheets should be used as indicative only for material selection purposes and not be utilized as specification or used for part or tool design.
