Description of Sulfur Hexafluoride

Sulfur Hexafluoride gas is a colorless, odorless, nontoxic, nonflammable gas that is used as an insulating gas in electrical equipment. At atmospheric pressures, sulfur hexafluoride gas sublimes directly from a solid to a gas. It is shipped as a liquefied compressed gas. Sulfur hexafluoride gas is used for leak detection and as a gaseous dielectric for transformers, condensers, and circuit breakers. Sulfur hexafluoride gas is highly effective as an etchant in the semiconductor industry.

Sulfur Hexafluoride has a commercial grade purity of 99.8%; AGP can provide higher purity SF6; a number of options are available below, please contact us for additional information.
