Green Gas for Grid - g3 - SF6 Free Solutions 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.
Sulfur Hexafluoride (SF6) electronic grade | Solvay is applied in the above process as an etching gas. Due to the density and large molecule size, SF6 is a preferred etching gas in flat panel and MEMS production processes. Fluorinated gases, such as Sulfur Hexafluoride (SF6), play very important roles in the manufacturing of silicon devices.

Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
