NORYL™ Resin BN31
SABIC's Specialties Business NORYL™ BN31 resin is a non-reinforced blend of polyphenylene ether (PPE) + polystyrene (PS). This blow moldable grade contains non-brominated, non-chlorinated flame retardant and carries a UL94 flame rating of 5VA at 2.5mm and V0 at 1.5mm along with a UL746C Outdoor Suitability rating of F1. NORYL™ BN31 resin exhibit good low temperature impact strength, heat resistance, excellent processability, Low warpage, and dimensional stability. The material is an excellent candidate for blow molded applications such as hospital bed headboard, cladding, tray.
