Recently, other alternatives to standard nylon monofilament lines have been introduced made of copolymers or fluorocarbon, or a combination of the two materials.
Another technology which is becoming popular again is special fluorocarbon liquids with high boiling points which use a method called vapor phase reflow.
Unfortunately, the term fluorocarbon is used rather loosely to include and chemical containing fluorine and carbon, including chlorofluorocarbons, which are ozone deleting (for example).
By contrast, fluorocarbon based compounds are fluorinated for specific chemical, physical, and sometimes biological reasons, as they have properties that are very distinct from hydrocarbons.
