Raymond, vinyl is the common name for polyvinyl chloride or PVC it's
dielectric constant at 1MHz is 4-5 and it's dielectric strength is 685
volts per mil BUT it's power factor is a wooping 120 at 1 MHz, that is
really bad this stuff absorbs R.F. like crazy! This stuff is worse than
mylar, it's definately NO GOOD for Tesla coil capacitors.
