Sulphur Hexafluoride 3.0

SF6 is an inert and high density gas.


Sulphur hexafluoride has found many industrial application utilising its extreme non-conductivity and high density properties. For instance, switch gears can be made smaller than using air as an insulating gas.


  • Insulator in circuit breakers and switch gears
  • In glass double glazing for heat and sound insulation
  • Leak detection
  • Tracer gas for testing geosequestration effectiveness
