Application

1. Dielectric medium: SF6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs. 

2. Medical use: SF6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations[9] in the form of a gas bubble.

3. Tracer compound 

4. Other uses: as an etchant, as inert gas to fill casting forms, as a filler gas in tennis balls and so on.
