Five excellent characteristics of perfluoropolyether grease
Perfluoropolyether grease, compared with hydrocarbon polyether, has the advantages of high density, low surface tension, low volatility, good viscous fluidity, non-combustibility, good dielectric properties, good lubricity, etc., and can be combined with plastics and rubber , The metals are well compatible.
Perfluoropolyether molecules only contain three elements: C, F, and O. Fluorine atoms have strong electronegativity, and most of the carbon chain is shielded by fluorine atoms. Compared with hydrocarbon polyethers, it has a higher density; it has five major advantages. feature.
1) Chemically inert
It shows strong chemical inertness to most corrosive chemicals such as acids, alkalis and oxidants. Some nucleophiles, active metals and Lewis acids can decompose perfluoropolyether and reduce its thermal stability.
2) Thermal oxidation stability
In the absence of an effective catalyst, even in the presence of oxygen, perfluoropolyether is still very stable in the range of 270-300. Its decomposition temperature can reach 350-410.
3) Compatibility
Perfluoropolyether has compatibility with many substances, and perfluoropolyether has good compatibility with plastics and artificial rubber.
4) Flame resistance
Flame resistance is an important condition for perfluoropolyethers suitable for industrial and aviation lubricants. Compared with other types of lubricants, it is more suitable for high temperature and harsh operating environment.
5) Radiation resistance
It has good radiation resistance, and under the same dose, compared with hydrocarbons and silicone oil, the viscosity growth rate is the lowest.
