Alfred & All,
For one thing it's VERY tough stuff, and as a result very diffficult to
strip using abrasive paper. If the spool is labeled it may also say
"TZT" or M/R TZ (Thermaleze, and moisture-resistant Thermlaleze) or APTZ
(Armored Polythermaleze) - all Phelps Dodge trade names. You can get it
in 1, 2, or even 3-layers of insulation (single, heavy, or single AND
heavy!). It's a ligher color than Formvar, being almost a straw-color.
It is very good, high-dielctric strength AND high temperature stuff!
