[cool][#0000ff]Most differences are at the molecular level. The polymers in PVC are more elastic and flexible, so they respond more to variations of temperature and pressure. You can make a bigger balloon with PVC of the same thickness than you can with one of urethane. Rigidity equals strength...under the same set of conditions...or so it would seem.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]And, as I suggested in my previous statements, the PVC materials degrade faster over time, so they do not last as long. In tuber's years, that might not mean much except added peace of mind...especially for the BOZO who insists on keeping their craft aired to the max, even on hot days and when travelling inside a vehicle.[/#0000ff]

[#0000ff]KABOOM.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]My riddle for you...If you dropped a democrat and a republican off the roof at the same time, which would hit the ground first?[/#0000ff]

[#0000ff]Who cares?[/#0000ff]
