PPO (polyphenylene ether)

Product name Polyphenylene ether dimethyl phenol, also known as polyphenylene oxide. English abbreviations. Polyphenylene ether is an amorphous material, and its working temperature is roughly ℃ to ℃. It has high impact toughness, low water absorption, high dimensional stability and is not prone to creep. Its electrical performance is basically not affected by the loading frequency, so it can be widely used in the electrical field. The main characteristic structure is glass transition temperature of about ℃, melting temperature of about ℃, and density/cm. The molecular weight of practical polyphenylene ether is ~ 10,000, and the crystallinity is about 10,000. The most outstanding advantage is its high water and steam resistance. After being treated in a high-pressure steam container at ℃ for several times, the tensile and impact strength do not change significantly. In addition, it has the characteristics of good dimensional stability, small creep, and high insulation. The long-term use temperature is ~ ℃, and the intermittent operation without load can reach ℃. , which is equivalent to that of general thermosetting plastics. Polyphenylene ether is produced by oxidative coupling polymerization of dimethylphenol in air or pure oxygen under the action of a copper salt such as cuprous chloride and a binding catalyst of an amine.
Advantages Good dimensional stability, low creep, heat resistance, no deformation, high impact resistance, toughness, low water absorption, good electrical properties in a wide frequency range, not easy to hydrolyze, easy to bond, very light weight.
Application fields Polyphenylene ether is easy to process and form, and can be extruded, injected or molded. It is used to replace stainless steel in the manufacture of medical devices, can withstand steam sterilization, and is also used in insulation materials for mechanical and electronic parts. The blended modified product of polyphenylene ether and polystyrene has the trade name in the United States, and can be reinforced with glass fiber, carbon fiber, etc. It is an engineering plastic and insulating material with excellent performance.
