描述
NORYL EFN4230S Resin is a high heat, transparent, non-reinforced blend of polyphenylene ether (PPE) and general purpose polystyrene (GPPS), manufactured by SABIC. This injection moldable grade is FDA Food Contact compliant and is an excellent candidate for food and industrial packaging applications. The “S” designation indicates this is the FDA compliant version; for non-FDA applications, refer to NORYL EFN4230.
The material offers high heat resistance (HDT of 147°C at 1.82 MPa), excellent dimensional stability, low warpage, low moisture absorption (0.07% water absorption at 23°C/24hrs), and hydrolytic stability. This product does not contain PFAS intentionally added during the manufacturing process. Physical property data is determined using test methods established by ASTM International, the globally recognized standards organization.
