Perfluoropolyether grease is made by adding ultra-fine polytetrafluoroethylene particles to the perfluoropolyether lubricating oil to make it thicker. It was initially used in space shuttles. The space shuttle is in a space environment, the rocket liquid oxygen engine generates a lot of heat during operation, and the turbo pump works at high temperatures.
The reason why perfluoropolyether is suitable for these extreme environments is that perfluoropolyether grease itself can meet the lubrication requirements of the space shuttle through good high and low temperature performance, oxidation resistance, radiation resistance, and chemical stability. It has become an indispensable part of the aerospace industry.
Perfluoropolyether grease has been widely used not only in cosmic lubrication, but also in private industries. Due to its excellent high-temperature characteristics, it has also been widely used in textiles, printing and dyeing, 3D printing, food processing and other industries.
