Sulfur Hexafluoride Supplier to Northern Illinois

Weldstar, the preferred provider of this colorless, odorless, liquefied gas in Northern Illinois, ships it in cylinders and tube trailers under its own vapor pressure, as prescribed by accepted industry standards and practices.

Sulfur Hexafluoride (SF₆) is normally prepared in batches through the direct fluorination of high-purity sulfur.

Sulfur Hexafluoride’s relatively high density and inactivity are what make it preferable for employment as an electrical insulator in high-voltage transformers, transmission lines, and microwave antennas. It is equally useful as an insulating gas in double-windowpane glass. Being a high-density inert gas is quite often as significant a limitor for SF6 as it is a strength; its Global Warming Potential (GWP) is considered problematic. That being the case, there is some level of active research to come up with a less environmentally destructive substitute to lessen its use. At this juncture, it is still widely accepted as the best insulator for high-voltage applications, but it ought to be applied wisely and returned for reclamation instead of just vented in the process of repairing equipment.

High-purity Sulfur Hexafluoride is used extensively as an etchant in semiconductor production, as a controllable source of fluorine.
