Does anyone know where I can buy some polyethylene washers?

I have looked in McMaster Carr, WW Granger and a few other places and have
found plastic washers but can not find out if they are differently made out
of polyethylene.

I am building a simple industructable capacitor using a fish aquarium,
several metal plates bolted together with all thread polyethylene rods,
polyethylene hex nuts, polyethlene .125 washers as spacers between the
plates and about 3 gallon of high voltage oil.

Wonder if some other type of plastic washer would work?

The flat washers need to be .125" thick or 2 washers in a stack .0625" thick
each.  Hole diameter can be .187" or .250".  Outside diameter is not very
important as long as all the washers are the same.

If this works as well as I think its going to then I will have some round
metal plates laser cut to fit the inside of a 4" PVC pipe.  Then capacitors
can be made any uf value I need just by using the correct number of metal
plates.  Fill it with HV oil and glue on the end caps with electrical studs.
