Description

Fluorolube Grease, Gr-362 is a high-performance, fully fluorinated synthetic lubricant based on polychlorotrifluoroethylene (PCTFE) oil thickened with PTFE. This formulation delivers exceptional chemical inertness and thermal stability, making it a critical component for demanding industrial applications where conventional hydrocarbon or silicone greases fail. It is essential for industries requiring reliable lubrication under extreme chemical exposure, high vacuum, or wide temperature ranges. Key sectors include semiconductor manufacturing, aerospace, chemical processing, and analytical instrumentation.

Application

• Vacuum System Seals & Valves: Primary lubricant for O-rings, seals, and valves in high-vacuum and ultra-high-vacuum (UHV) environments due to its extremely low vapor pressure.
• Chemical Process Equipment: Lubrication of pumps, bearings, and threaded connections exposed to aggressive chemicals, strong acids, strong alkalis, and solvents.
• Semiconductor & Wafer Fabrication: Used in wafer handling robots, chamber seals, and vacuum pumps within etch and CVD tools where purity and outgassing resistance are paramount.
• Oxygen Service & Aerospace: Safe for use in oxygen-rich environments and aerospace applications due to its non-flammability and compatibility with most oxidizers.
• Analytical & Laboratory Instruments: Lubricant for stopcocks, joints, and seals in spectrometers, chromatographs, and other sensitive equipment.
• Extreme Temperature Bearings: Lubrication for bearings and slides operating in cryogenic conditions or at elevated temperatures where thermal breakdown is a concern.
