Fluorocarbon

Perfluorohexane is a common cooling agent, and a solvent. Its is a fluorocarbon.

Fluorocarbons are chemical compounds that only contain fluorine and carbon. The terminology isn't strictly followed, many organic compounds are called fluorocarbons. Another name is Perfluorocarbon. Fluorocarbons belong to the group of hydrofluorocarbons. Fluorocarbons are commonly used in insulation, and as cooling agents, called refrigerants. Because they take a long time to decay, they are considered greenhouse gases.
