Perfluoropolyether grease is a white perfluoropolyether grease made from polytetrafluoroethylene (PTFE) thickened with a highly chemically stable perfluoropolyether oil (PFPE) and refined with special anti-corrosion additives. This fluorine-based high-temperature grease is specifically designed for bearings in high-temperature, high-load, and chemically corrosive environments, as well as for components requiring lifetime lubrication. It exhibits excellent chemical inertness, durability, and low volatility. Its applicable temperature range is -50°C to +280°C.
