Perfluoropolyether is widely used in the chemical industry, and its unique physical and chemical properties make it an ideal material for many fields.The following are the main applications of perfluoropolyether in the chemical industry：

Application of vacuum pump：
Perfluoropolyether oil is used as a working fluid in various vacuum pumps, such as rotary pumps, turbomolecular pumps, and steam diffusion pumps.When corrosive gases (such as liquid oxygen and gas, halogen, sulfur anhydride, etc.) are present in the operating environment, perfluoropolyether oil is used as a lubricating oil for compressors and valves.
Application of magnetic media industry：
Because of its low coefficient of friction, low volatility and good insulation, perfluoropolyether oil is used as a lubricant for hard disks, magnetic tapes and other magnetic recording media on computers, video recorders, automatic recording devices and other instruments.
Application in the electronics industry：
In the process of using plasma etching, LPCVD and plasma cultivation technologies to produce semiconductor materials, perfluoropolyether oil is used as a lubricating oil for vacuum mechanical pumps, and has achieved widely satisfactory results.
