Perfluorocyclobutane is colourless, non-toxic, pungent odour, non-flame gas
Is used for used for electron gas, glasses processing, medcine, and other field C318 is used as propellant in food industry, refrigerant, cleaning agent, dielectic (mixture with SF6); media of polymerization of fluorine-contained polymers; etchant of IC.
In the electronics industry, octafluoropropane is mixed with oxygen and used as a plasma etching material for SiO2 layers in semiconductor applications, as oxides are selectively etched versus their metal substrates.

octafluoropropane may compose the gas cores of microbubble contrast agents used in contrast-enhanced ultrasound. Octafluoropropane microbubbles reflects sound waves well and are used to improve the ultrasound signal backscatter. It is also used in pars plana vitrectomy procedures where a retina hole or tear is repaired. The gas acts to provide a long-term tamponade, or plug, of a retinal hole/tear and allows re-attachment of the retina to occur over the following several days post-op.
Under the name R-218, octafluoropropane is used in other industries as a component of refrigeration mixtures.
