  • SF6 Gas Use in Electrical Applications - Sulphur Hexafluoride

    Sep 03, 2018Sulphur hexafluoride (SF 6) is a man-made gas comprising of one sulphur and six fluoride atoms.SF 6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and

  • Sulfuryl Fluoride General Fact Sheet

    When released, sulfuryl fluoride rapidly spreads out through the air and into the atmosphere. Its lifetime in the atmosphere is estimated to be 4.5 years or more. After a single emission, this is the average amount of time it would take to return to pre-release levels of sulfuryl fluoride in the atmosphere.
