High temperatures often present the most demanding test for lubricating greases. Ordinary greases decompose and evaporate at temperatures around 200°C, rapidly degrading their lubricating properties and even causing
equipment to seize. However, perfluoropolyether grease (PFPE grease) can operate stably and long-term at high temperatures. Why is this so?
The secret lies in its chemical structure. The bond between the carbon and fluorine atoms in perfluoropolyether molecules is extremely high, making it one of the most stable chemical bonds in organic compounds. This strong bond makes the molecular chain difficult to break even at high temperatures, thus ensuring the grease's thermal stability.
Furthermore, perfluoropolyether grease contains almost no hydrogen and is therefore not easily oxidized. This means that even in high-temperature air, it is unlikely to generate harmful byproducts such as carbides and acidic substances, maintaining its lubrication performance for a long time.
In addition, its volatility is extremely low. In high-temperature environments, ordinary lubricants will gradually evaporate, resulting in insufficient lubrication, while PFPE grease can still maintain a stable oil film, continuously protecting key components such as bearings and gears.
It is precisely because of these properties that perfluoropolyether grease is widely used in aerospace, semiconductor, chemical and food high-temperature baking equipment, becoming a reliable choice for coping with extreme working conditions.
