	CPVC is Chlorinated PolyVinyl Chloride. Its main difference
	from PBC is that it viable for hot-water plumbing, where PBC
	pipe is only good for cold water. (PVC is ok up to 60deg C,
	CPVC up to 82deg C.)

	Radiation tolerance wise, when our shop left, the plastics
	catalogs went with  them, but many plastics suppliers have
	sections listing various plastic properties. I'd opt  for a
	call to a local supplier.
