Perfluoropolyether series
Perfluoropolyether, referred to as PFPE, is a colorless, odorless, transparent liquid at room temperature. The molecular composition contains only C, F, O three elements, because the F ion has a strong electronegativity, the bond energy is as high as 418~502 kJ/mol, the main chain of C- C, C- O-C bonds are mostly shielded by F atoms.

Perfluoropolyether fluid is a perfluoropolyether product with low degree of polymerization, low molecular weight, low boiling point and low viscosity. It is heat-resistant, oxidation-resistant, non-flammable, has good material compatibility and is insoluble in general organic solvents. Compared with other fluorine fluids on the market (hydrofluoroethers, hydrofluorocarbons, perfluorinated hydrocarbons, perfluorinated ketones), it is more stable in nature and more environmentally friendly than perfluorinated hydrocarbons.

Perfluoropolyether oil is a colorless and transparent oily liquid at room temperature. It is resistant to high temperature, chemical corrosion, oxidation and radiation. It is mainly used as lubricating oil and vacuum pump oil. Due to its high stability and safety, especially the high reliability when working under particularly harsh conditions, no working medium can be comparable to perfluoropolyether oil in such a harsh environment.
