How much do you know about the "noble among oils" perfluoropolyether grease?

Today, Jialede will take you to deeply understand the "noble" in lubricating oil - perfluoropolyether grease. Perfluoropolyether (PFPE, English name Perfluom Polyethers) was first studied in the 1960s and is a relatively special type of perfluoropolymer compound. Its average molecular weight ranges from 500 to 15,000. There are only three elements, C, F, and O, in the molecule. It has the characteristics of heat resistance, oxidation resistance, radiation resistance, corrosion resistance, and non-flammability. It is used as an extremely reliable lubricant in cutting-edge fields such as military, aerospace, and nuclear industry. Today, perfluoropolyether is widely used in chemical, electronic, electrical, mechanical, nuclear, and aerospace fields.Because the fluorine atoms in perfluoropolyether have strong electronegativity, most of the carbon chain is shielded by fluorine atoms. Compared with hydrocarbon polyethers, it has the advantages of high density, low surface tension, low volatility, good viscosity, non-flammability, good dielectric properties, good lubricity, and is well compatible with plastics, rubber, and metals. It is a low molecular weight fluorinated polymer, and its viscosity is closely related to its molecular structure and average molecular weight. PFPE with a larger molecular weight has low volatility, a wider liquid temperature range and excellent viscosity-temperature characteristics. Jialede perfluoropolyether grease has a stable molecular structure, and its high temperature resistance, fire resistance, radiation resistance and chemical resistance are also particularly excellent. It is suitable for lubricants under strong chemical conditions. However, the price of perfluoropolyether grease is relatively expensive due to its material.
