Used primarily as a highly stable, non-reactive fluid in specialized industrial applications. Its strong carbon-fluorine bonds make it ideal for use in extreme environments, such as in high-performance lubricants and heat transfer fluids where thermal and chemical resistance are critical. Commonly found in aerospace and semiconductor manufacturing equipment due to its inertness and ability to withstand high temperatures. Also employed in oxygen-rich systems because of its resistance to combustion. Additionally, it serves as a surfactant carrier or processing aid in fluoropolymer production and can be used in some medical device applications requiring biocompatible, non-toxic fluids.
