Why insulating gas or Sulfur Hexafluoride gas is better for arc

Sulfr hexafluoride decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into gaz sf6 so well that it is not necessary to replenish the gaz sf6 in GIS. There are some reactive decomposition byproducts formed because of the interaction of sulfur and fluorine ions with trace amounts of moisture, air, and other contaminants.
