Dear Technet friends,

We've been using tefzel (a modified teflon) insulated wires in our transformer
assemblies. Some people are concerned that the teflon's cold-flow property would
end up in shorts between windings where there are pressure points. My questions
are:

- Is tefzel better than the unmodified teflon in this respect?
- How is the cold-flow characteristic quantified?
- Where can I find the "cold-flow index" of the materials?

Yours sincerely
