P.V.C has a very high dissipation factor, they actually use radio
frequency to weld P.V.C. (albeit at a very high frequency) I do not
recall the exact figures but polyethylene and styrene both have rather
low dissipation factors.  (anyone have a C.R.C. handbook handy?)

Ideally no core at all would be best, Styrofoam is about as close as
your going to get to no core at all.

We have had many strikes but no fires or burning foam, not even a hint
of burning styrene in the air. I don't think that the heat from the
strike gets trapped behind the windings like it does with P.V.C.
