Used primarily as a synthetic lubricant base stock in high-performance applications. Offers excellent thermal stability and resistance to oxidation, making it suitable for use in jet engines, gas turbines, and other demanding aerospace systems. Commonly found in greases and hydraulic fluids where long service life and reliability under extreme temperatures are required. Also used in biodegradable lubricants due to its favorable environmental profile. Its low volatility and high viscosity index support consistent performance across a wide temperature range.
