Valiant I think is the major user of PU in the mainstream market and they quote repeatedly that their seams are stronger then their tubes, and that PU is of theoretically a higher specification that hypalon. In what way - longetivity strength etc - I don't know!

Ummmm....

I'm pretty sure you will find that PU is glued, while PVC is welded? Like I said earlier, don't be put off by PU (polyurethane) - it is good stuff. When gluing, acetone is the secret ingredient to make a good bond.... you have to rub the PU HARD with acetone before gluing, but other than that, it is much like working with hypalon.

All IMVHO of course.... but I love my XS!

Chewy,

Sorry, didn't make that very clear - was talking about the manufacturing process. But yes, you can glue PVC too...

Regards

Mike
