NORYL NH4050 resin is a non-reinforced blend of polyphenylene ether (PPE) + polystyrene (PS). This injection moldable grade contains non-brominated, non-chlorinated flame retardant and carries a UL94 flame rating of V0 at 1.5mm along with UL746C Outdoor Suitability rating of F2. This material also exhibits chemical resistance to battery acids, hydrolytic stability, high impact and heat resistance, and low specific gravity for light-weight parts. NORYL NH4050 resin may be an excellent candidate for lead acid battery housings, covers, and enclosure applications.
