The next level from paper dielectric was mylar. Mylars can be epoxy
dipped usually green dipped, polypropolene is widely used orange
dipped epoxy, and the asian rim caps are brown dipped epoxy. That's
one good way to tell by the color of the epoxy.

I was at a hamfest looking for some mylar caps for a circuit that called for
them. I got several opinions on how to tell one and finall gave up. Are
there any sure fire ways to identiy a cap as mylar and why are they bettter
than a silver mica or others. Does anyone have a short chart comparing the
characteristics? How did we get by before mylar was used?
tnx
