描述
NORYL 731F resin is a non-reinforced blend of polyphenylene ether (PPE) and high impact polystyrene (HIPS). Manufactured by SABIC, this injection moldable grade is NSF/ANSI 61 listed for potable water use and FDA Food Contact compliant. It exhibits good surface appearance, high ductility, and good impact resistance along with low moisture absorption, creep resistance, dimensional stability, and hydrolytic stability. NORYL 731F resin is an excellent candidate for a variety of water management applications such as valves, filtration components, and water meter internals.
The “F” designation indicates this grade is FDA Food Contact compliant and NSF/ANSI 61 listed for potable water use, making it suitable for applications requiring regulatory compliance for food and water contact. This product does not contain PFAS intentionally added during the manufacturing process. Physical property data is determined using test methods established by ASTM International and ISO, the globally recognized standards organizations.
