fluorocarbon Chem.|ˌfluːərəʊˈkɑːbən|
[f. fluoro- + carbon, after hydrocarbon.]
Any of a large class of synthetic, chemically stable compounds of carbon and fluorine analogous to the hydrocarbons (see also quot. 1962).

I. xii. 402 Substances made from or protected by fluoro⁓carbons are free from decay and insect damage. 1951Sci.

Fluorine vii. 57 In the technical literature there has developed a tendency to use the term ‘fluorocarbon’ to include compounds containing elements additional to carbon and fluorine, e.g. CF2Cl2. This practice is confusing and is to be deprecated. 1964R. E.
