PPO 沙伯基础(原GE) 731-701 (CAS No.None)

Product Name:Polyphenylene Oxide (PPO) SABIC 731-701

English Name:Polyphenylene Oxide (PPO) SABIC 731-701

CAS No.:24938-67-8

Aliases:Polyphenylene ether (PPE), Poly(2,6-dimethyl-1,4-phenylene oxide), NORYL 731-701

Molecular Formula:(C8H8O)n

Physical Properties:Non-reinforced flame-retardant polyphenylene oxide/polystyrene alloy with a density of about 1.07 g/cm³, low water absorption and excellent dimensional stability. It has a heat deflection temperature of 90–100°C (at 1.82 MPa), long-term service temperature of 80–105°C, and tends to decompose when heated above 330°C. It exhibits good mechanical strength, resistance to stress relaxation, creep resistance, heat resistance, water resistance, steam resistance and dimensional stability.

Uses:Used in electronic and electrical, automotive, mechanical and chemical industries. Suitable for manufacturing housings, chassis and precision parts of office equipment, home appliances and computers, as well as medical devices, hot water storage tanks and mixing valve fillers in exhaust fans, replacing stainless steel and other metals.
