not sure on pvc, isnt it stiff? silicone is nice. super flexible, maybe even more so than tygon. ive never seen it totally clear, but it does come transluscent. usually opaque tho. it does have a bad problem with vapor exchange tho. youll need to refill//top-off the loop alot more often if your using silicone over something like tygon.

So what is tygon made of then, PVC or something else?

Tygon doesn't say on their site what the tubing is made of. I'd speculate a polyurethane based plastic though. As for tubing, it depends on how long a piece of string is. I've not used silicone tubing, only various types of PVC. Your average home despot / B&Q store carries less than decent stuff. goes hard after a few months, maybe a bit misty, kinks easy. I've just got some thicker walled stuff today (see under my UK suppliers post) which I'm going to be trying out soon.
