I introduced Tefzel as being a wire and connector specialist, but it's so long back that my poor cells have forgotten most, however, as far as figure it out, the change from Teflon to Tefzel was the considerable price difference. We never had Tefzel cold-flow problems in our MIL equipments.

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
