NORYL™ Resin 731S
SABIC's Specialties Business NORYL™ 731S resin is a non-reinforced blend of Polyphenylene ether (PPE) + polystyrene (PS). This injection moldable resin is FC EU, FDA food contact compliant and has NSF/ANSI 61, ACS, WRAS, and KTW/W270 listings for selected colors and manufacturing locations. NORYL™ 731S resin exhibits good surface appearance, high ductility, low moisture absorption, dimensional and hydrolytic stability. NORYL™ 731S resin is an excellent candidate for a variety of water management applications such as valves, filtration components, and water meter internals. 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.

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.; ᵖ UL ratings shown on the technical datasheet might not cover the full range of thicknesses and colors. 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.
