I don't have experience with this, but I have used many polystyrene
capacitors in the past (low voltage stuff).  They appear to be a roll of
poly and foil, which has been fused so that the ends are completely
sealed.  The leads are usually axial, and the poly has been melted onto
the wires to support them.  The whole thing must be fused solid, because
there is no outer covering - the capacitance and voltage is simply
printed on the outer poly.  For what it is worth...
