Bert, Chris,
Another very unpleasant aspect of polystyrene I've noticed is a
horrible tendency to burn and char from corona effects. Whereas
polyethylene simply melts due to corona (at least at first), the
polystyrene immediately burns and becomes completely
conductive and non-salvageable. I use this material
sometimes for form materials for high powered tube coils, but if
the coils ever flash over...that's the end of the polystyrene form.
