About PVC & ORCA® CSM (Hypalon)

​

Almost all inflatable boats are constructed with either PVC or CSM/Hypalon fabric. Hypalon was discontinued by its manufacturer (DuPont) and is now sold under its slightly different formula and new name "CSM" or Chlorosulfonated Polyethylene Rubber.

Our boats are made with either PVC (Mehler-Valmex® PVC from Germany) or Orca® CSM (Hypalon) from France. Each fabric has their advantages and disadvantages. Both fabrics should be considered when making your selection. 

PVC fabric is known to be significantly less expensive than CSM. PVC is quite strong and can come in different thicknesses such as .09mm & 1.2mm, but this still does not change the fact that it does not repel sunlight as great as CSM. It can definitely be kept in great shape and last just as long if well maintained. 

CSM on the other hand is more expensive overall but will last longer and is excellent against sun exposure & tolerant on fuel spills or fumes. CSM is simply longer lasting, more expensive and has a high tolerance through a variety of environments or different weather.
