Applications: Gaseous dielectric for high voltage power, gas density switches, insulated switchgear and circuit breaker, semiconductor (etching of silicon oxides and CVD/PECVD chamber clean), aluminum and magnesium degassing, ultra-sound imaging, double pane windows, leak detection.

Additional information: Sulfur Hexafluoride (SF6) is a colorless, odorless, nonflammable, nonreactive, relatively nontoxic gas which acts as a simple asphyxiant by displacing air. Sulfur Hexafluoride is shipped as a liquefied gas under its own vapor pressure (298 psig @ 21C).
