Perfluoropolyether

Perfluoropolyether (PFPE) is a type of liquid lubricant used in the Aerospace industry for over 30 years. The main properties of PFPE are being temperature resistant between 215 K - 530 K (depending on specific composites), having very low outgassing compared to other fluids (vapour pressure of 6e-8 torr) and having a dielectric strength of around 15.7 MV/m.
