In these cases [where PVC is undesirable], it is necessary to use a more robust insulating material such as fluorine or silicone.

Fluorine, really? Definitely not my choice for an electrical insulator.

...wood and water spontaneously combust under a fluorine jet.

However, I do like Kynar (a fluorinated hydrocarbon). Fairly easy to strip, is usually thinner than PVC, and doesn't shrink back or discolor like PVC does.[/quote]

 

I wonder if by fluorine they mean Teflon.

They are not the same, just as silicon and silicone are not the same. It was sloppy writing and/or translation. As for Teflon insulated wire , it has its uses, but as mentioned, I prefer Kynar, which is a partially fluorinated hydrocarbon.
