Contribution of perfluoropolyethers in vacuum industries

Perfluoropolyethers from hexafluoropropene photooxidation, are characterized by attractive physical and antiwear properties of chemical and thermooxidative stability, so as to allow their use as vacuum working fluids and as a base for high vacuum grease.The vacuum technologies, where residue pressures of aggressive chemical agents are involved, can benefit by the unique fluid's performances.
