Hypalon

Tubes made of hypalon (csm/cr) are easy to manufacture and can be repaired with simple puncture repair kits. Hypalon (csm) is not airtight and so must be combined with neoprene (cr) when used to build tubes. Tubes made with Hypalon and Neoprene layers can last up to twice as long as PVC tubes and have been known to last over 20 years. Hypalon is probably the most popular material used for the construction of RIBs manufactured in the UK.

Polyvinyl chloride

Wannan ƙari yana narkewa yayin da kayan ke tsufa, yana sa PVC ya lalace kuma yana ba shi damar fashewa. Wani bututun PVC shine mafi arha kuma zai iya zama kusan shekaru 10-15.

PVC does have some advantages, it is cheap, it can be welded, and it is guaranteed for longer than hypalon. PVC RIBs are usually very well made and with welded seams they are less prone to blowouts and leaks.

A newer form of PVC has made its way into production. Known as valmex it is said to have a blackout layer on the inside to reduce UV damage to the adhesives usually used to fix tubes to the hulls and various other parts.
