Applications and Industries
- Refrigeration: Under the name R-218, octafluoropropane is used in refrigeration mixtures.
- Semiconductor Manufacturing: It’s used in plasma etching of wafers and cleaning of vacuum chambers in the electronics industry.
- Medical Imaging: It forms the gas cores of microbubble contrast agents in contrast-enhanced ultrasound, improving signal reflection.
- Eye Surgery: Used as a tamponade in retinal detachment repair procedures to help reattach the retina.
- Terraforming: Due to its high greenhouse gas effect (24,000 times greater than CO2), it has been proposed as a means to warm Mars.
- Dark Matter Detection: It is the active liquid in the PICO-2L dark matter bubble detector.
- Other Applications: Can also be used as a fire extinguishing agent, propellant for aerosols, and as a gaseous dielectric insulating medium
