Perfluoropolyether

Perfluoropolyether (PFPE) is a type of lubricant often used in the Aerospace industry. The main properties of PFPE are temperature resistant between 215 K - 530 K (depending on specific composites), very low outgassing compared to other fluids (vapour pressure of 6e-8 torr) and a dielectric strength of around 15.7 MV/m.[1]
