The development of new, low-cost perfluoroalkylether fluids with excellent low and high-temperature properties [PDF]

open access: yes
A series of perfluoroalkylether (PFAE) fluids were synthesized by direct fluorination. Viscosity-temperature properties, oxidation stabilities, oxidation-corrosion properties, and lubricity were determined.
