Used primarily as a highly stable, inert fluid in specialized industrial and scientific applications. Its extreme resistance to heat and chemical degradation makes it suitable for use in high-performance lubricants and hydraulic fluids, especially in harsh environments. Commonly found in aerospace and defense systems where thermal stability and non-flammability are critical. Also utilized in electronic testing as a dielectric fluid due to its excellent insulating properties. Frequently employed in research settings for surface coating studies and as a reference material in mass spectrometry because of its well-defined fluorocarbon structure. Its non-reactive nature allows safe use in sensitive instrumentation and vacuum systems.
