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 and 530 K (depending on specific composites), having very low outgassing compared to other fluids (vapour pressure of 6×10−8 Torr) and having a dielectric strength of around 15.7 MV/m.
The thermal and chemical stability of PFPE along with a vapor–liquid equilibrium of 230°C when mixed with the right composites make it a suitable candidate for vapor phase soldering technologies.
