Used as a high-performance lubricant in extreme environments due to its exceptional thermal and oxidative stability. Commonly applied in aerospace mechanisms, vacuum pumps, and precision instruments where long-term reliability is critical. Resistant to many chemicals and maintains performance across a wide temperature range. Also used in semiconductor manufacturing equipment and oxygen-rich systems because it is non-flammable and inert. Its low volatility makes it suitable for use in sealed systems and high-vacuum applications.
