introduction
perfluoropolyether (PFPE, English name Perfluom Polyethers) was first studied in the 2060s. it is a special type of perfluoropolymer compound with an average molecular weight ranging from 500 to 15000. there are only three elements of c, f and o in the molecule. it has the characteristics of heat resistance, oxidation resistance, radiation resistance, corrosion resistance and incombustibility, and it has been used as an extremely reliable lubricant in cutting-edge fields such as the military, aerospace and nuclear industries for decades. Nowadays, perfluoropolyether is widely used in chemical industry, electronics, electrical appliances, machinery, nuclear industry, aerospace fields.
features
Perfluoropolyether molecules contain only three elements, C, F, and O. Due to the strong electronegativity of fluorine atoms, most of the carbon chains are shielded by fluorine atoms. Compared with hydrocarbon polyethers, it has the advantages of high density, low surface tension, low volatility, good viscosity, non-combustibility, good dielectric properties, good lubricity, etc., and it can be well compatible with plastics, rubber, and metals. Perfluoropolyethers are low molecular weight fluoropolymers, and their viscosity has a great relationship with molecular structure and average molecular weight. PFPE with larger molecular weight has low volatility, wide liquid temperature range and excellent viscosity-temperature characteristics.
