I'd say that PVC is a fine material for coil forms, if it works. My
experience with using it has been generally good, but unpredictable
(that is, every once in a while you get a piece of junk). It's also
not the best structural material if it gets warm. There are other
inexpensive plastics that might be a good choice.
