[Conclusion] - Fluorinated grease is selected and used because of its advanced properties such as heat resistance, chemical resistance, and no effect on electrical contacts for which other lubricants' characteristics can't substitute. - Fluorinated grease is mainly used in the closed system of specific machines and parts for a long time. - Fluorinated grease is 10-1000 times more expensive than general-purpose grease.
