SABIC NORYL™ Resin 731S Polyphenylene Ether + PS (PPE+PS) (Asia)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene + Polyphenylene Ether, Unreinforced
Material Notes:	NORYL™ 731S resin is a non-reinforced blend of Polyphenylene ether (PPE) + high impact polystyrene (HIPS). 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. Information provided by SABIC
