描述
NORYL BN31 Resin is a non-reinforced blend of polyphenylene ether (PPE) and high impact polystyrene (HIPS), manufactured by SABIC. Designed for blow molding, it features a halogen-free flame retardant system (non-brominated, non-chlorinated) with UL94 V-0 (1.5mm) and 5VA (2.5mm) ratings, and carries a UL746C F1 outdoor weathering rating.
The material offers good low-temperature impact strength, heat resistance, excellent processability, low warpage, and dimensional stability, making it an excellent candidate for healthcare bed panels, building cladding, and pallets. Physical property data is determined using test methods established by ASTM International and ISO, the globally recognized standards organizations.
