OF-1 is widely used as a high-performance lubricant in extreme temperature environments. It exhibits excellent thermal stability and oxidation resistance, making it suitable for aerospace and vacuum applications where conventional oils fail. It is commonly applied in jet engines, spacecraft mechanisms, and precision instruments exposed to wide temperature ranges. Due to its low volatility and high load-bearing capacity, OF-1 also serves in long-life greases for critical mechanical systems. Additionally, it is utilized in specialized seals and O-rings where compatibility with aggressive fluids is required.
