Capacitor materials




  Now with the possibility of a transformer I started looking for
materials to make a good HV capacitor. So far the only PE sources I
found were super-thin plastic bags, too small for any actual use, and
kitchen foil, absolutely useless. I am still looking for it though… I
have some ideas: For instance, what material are those overhead
projector sheets made out of? They are just the right size for a good
plate cap and don’t cost too much… I can’t remember how thick they
are, but they are relatively thick. They are made out of some type of
plastic, fairly rigid and it goes white when you bend it at sharp
angles. HDPE perhaps?
 I also found some very thin paper, made to absorb oil from chips and
other fried foods. That paper looks like it would be absolutely
perfect to suck up oil between the capacitor’s plates plus it comes in
huge (50 meters long) rolls, 1meter wide. It’s very cheap too!
 And I got a gallon of model plane oil in the garage. It’s the oil you
add to model aeroplanes (and model cars, boats, helicopters, etc)
fuels to run their small 2-stroke engines. The fuel consists of
Methanol and this oil. Sometimes a little nitromethane too. It’s very
good quality and insulates HV well. It is not easily combusted (takes
something like 400C to get it to vaporise and be ignitable burning (so
you could say 400 is its flash point), at which temperature it also
starts to boil) What kind of oil could it be? It doesn’t say Castor
oil anywhere, the label just reads: “Premium quality synthetic oil for
2-stroke engines”…
 Well, please give me your thoughts on all that... I sure hope all
this stuff is good, because it would make such nice cheap
capacitors:-) And, where do you get PE normally?
