SABIC NORYL™ Resin EM7304F Polyphenylene Ether + PS (PPE+PS) (Americas)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene + Polyphenylene Ether, Unreinforced
Material Notes:	NORYL™ EM7304F resin is a 15% glass reinforced blend of polyphenylene ether (PPE) + high impact polystyrene (HIPS). This injection moldable grade has enhanced polyurethane foam adhesion and high flow along with creep resistance, dimensional stability, and hydrolytic stability. NORYL EM7304F resin is an excellent candidate for automotive interior applications such as instrument panel retainers. Features: Hydrolytic Stability,Low Creep Sensitivity,High Flow Information provided by SABIC
