C4F8 High Purity Plus Specialty Gases / Colourless Odourless Gas With −5.8 °C Boiling Point

Octafluorocyclobutane C4F8 , Perfluorocyclobutane Used As A Plasma Etching Material

Description:

Appearance, Safety Requirements: Octafluorocyclobutane is a colorless, odorless, non-flammable,
liquefied gas. R-318 is an asphyxiant and presents a significant health hazard by displacing the oxygen in
the atmosphere (see MSDS for further information).

In the production of semiconductor materials and devices, octafluorocyclobutane serves as a deposition gas and etchant. It has also been investigated as a refrigerant in specialised applications, as a replacement for ozone depleting chlorofluorocarbon refrigerants. Exploiting its volatility and chemical inertness, octafluorocyclobutane may be found in some aerosolized foods. It is investigated as a possible replacement for sulfur hexafluoride as a dielectric gas.

In medicine, octafluoropropane may compose the gas cores of microbubble contrast agents used in contrast-enhanced ultrasound. Octafluoropropane microbubbles reflects sound waves well and are used to improve the ultrasound signal backscatter. It is also used in pars plana vitrectomy procedures where a retina hole or tear is repaired. The gas acts to provide a long-term tamponade, or plug, of a retinal hole/tear and allows re-attachment of the retina to occur over the following several days post-op.

Under the name R-218, octafluoropropane is used in other industries as a component of refrigeration mixtures.
