SABIC NORYL™ Resin 731 Polyphenylene Ether + PS (PPE+PS) (Americas)
Categories: Polymer; Thermoplastic; Polystyrene (PS); Polystyrene + Polyphenylene Ether, Unreinforced

Material Notes: NORYL™ 731 resin is a non-reinforced blend of polyphenylene ether (PPE) + high impact polystyrene (HIPS). This injection moldable grade exhibits good surface appearance, high ductility, and good impact resistance along with low moisture absorption, creep resistance, dimensional stability, and hydrolytic stability. NORYL 731 resin is an excellent candidate for a variety of applications.

Features: Hydrolytic Stability,Low Creep Sensitivity
