The molecular structure of Perfluoropolyethers (Perfluoropolyethers, abbreviated as PFPE) lubricants is basically similar to that of hydrocarbon lubricants, but in PFPE molecules, fluorine atoms replace hydrogen atoms, thereby replacing the c—H bonds in hydrocarbons with stronger c—F bonds. And the presence of c—o and c—c strong covalent bonds, as well as the neutral characteristics of PFPE molecules, make PFPE have high thermal stability and oxidation stability, as well as good chemical inertness and insulating properties. PFPE with larger molecular weight also has low volatility, wider liquid temperature range and excellent viscosity-temperature characteristics. In addition, the main physical and chemical properties of PFPE polymers include: detection stability, biological inertness, low surface energy, good lubricity and compatibility with plastics, metals and artificial rubber
Application field PEPF perfluoropolyether oil can meet the application requirements of high temperature and high load in mechanical industry and automobile industry. High stability and good anti-wear ability make PEPF perfluoropolyether oil suitable for long service life and harsh operating conditions Lubricants under:
Chemical industry: PEPF perfluoropolyether oil is used as a working fluid in various vacuum pumps (rotary pumps, turbomolecular pumps and vapor diffusion pumps); there are corrosive gases (such as: liquid oxygen and gas oxygen, halogen, sulfur) in the operating environment Crisp, etc.) exists, PEPF perfluoropolyether oil is used as lubricating oil for compressors and valves
Electronics industry: Some vacuum mechanical pumps are used in the production of semiconductors by using plasma etching, LPCVD and plasma implantation technologies, and PEPF perfluoropolyether oil is used as a lubricating oil for vacuum mechanical pumps to achieve better results;
Mechanical industry: PEPF perfluoropolyether oil is often used as high temperature and chemically stable porous metal bearing conveyor belt, papermaking and textile machinery lubricants, when used as plastic bearing lubricants, its anti-wear ability is greatly improved, when some electromechanical equipment PFPE lubricating oil is often used when good lubrication and arc resistance are required (like current contactors, switch buttons and sliding electrical contactors, etc.);
Aerospace industry: Because PEPF perfluoropolyether oil has a wide liquid temperature range, low evaporation, high static viscosity, very low vapor pressure, low flow temperature and good high-pressure lubricity, it has been widely used in the aerospace industry application;
Magnetic media industry: low friction coefficient, low volatility and good insulation make PFPE can be used for lubrication of hard disks, tapes and other magnetic recording media on computers, video recordings, automatic recording devices and other instruments;
