Hi Jim

Even 101 nylon has a problem like that. When you machine it after its
been sitting on the shelf for a few months you find the diameter has
increased from water absorbtion.

Bob,
Have just wound a coil on 4" grey UPVC, but before I did I whacked it into
the microwave, and it certainly didn't show any signs of warming.
Maybe they have removed the carbon?
