聚苯醚PPO沙伯基础731S-111材料 (CAS No.None)

Product Name:Polyphenylene Oxide (PPO) SABIC 731S-111 Material

English Name:Polyphenylene Oxide (PPO) SABIC 731S-111 Material

CAS No.:25134-01-4

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

Molecular Formula:(C8H8O)n

Physical Properties:Low density, relative density approximately 1.06 g/cm³; melting point approximately 268°C, with a tendency to decompose when heated to 330°C; excellent mechanical strength, stress relaxation resistance, creep resistance, heat resistance, water resistance, steam resistance, and dimensional stability.

Uses:Pure PPO has poor melt flow, so commercial products are mostly modified grades with excellent overall performance. It is widely used in electronics and electrical applications to produce TV tuner pieces, coil cores, microwave insulation parts, shielding sleeves, high-frequency printed circuit boards, and high-voltage electronic components; in the automotive industry for instrument panel parts, window frames, shock absorbers, and pump filter screens; in mechanical engineering for gears, bearings, pump impellers, and fan blades; and in chemical applications for corrosion-resistant parts such as pipes, valves, filter plates, and submersible pumps.
