Perfluoropolyether (PFPE) was first studied in the 1960s. It is a special kind of perfluorinated polymer compound with an average molecular weight ranging from 500 to 15,000. Non-flammable and has been used for decades as an extremely reliable lubricant in cutting-edge fields such as the military, aerospace and nuclear industries.
Perfluoropolyether does not react with most corrosive chemicals such as acids, alkalis and oxidants, and shows strong chemical inertness. However, some strong nucleophiles, such as dry ammonia and active metals such as Al, Mg, Na, K, etc., can decompose perfluoropolyether and reduce its thermal stability.
Perfluoropolyether is widely used in the fields of chemical industry, electronics, electrical appliances, machinery, nuclear industry, and aerospace.
