This has been discussed before but Im after a nice clear definitive answer, so here goes again:

Whats the difference between "PU" and "PVC" and which is better/stronger/more long lasting/easier to keep looking nice.


Edit: this is for tubes just in case it wasn't clear....

I've done some searches on this. The info on rib fabrics in this wikipedia article seems to be consistent with what I've read from various other sources.

How long does PVC last?

It says on that site it will last for five years, mine is 8 years old and still ok.

My Lodestar is 1998, the tubes have never been repaired theres no leaks.

It has spent most of its time inflated and I have probably deflated it twice in the past year. It doesn't seem brittle. The things that have suffered is a couple of handles have gone sticky? The plastic seems to be breaking down.

Hopefully I'll get a proper rib next year...
