Advice \ How to identify inflatable boat material

It is very important to use the correct adhesive for the material. There are two main types of material used in the manufacture of inflatable boats.

1. Hypalon:- this is a rubber/neoprene material
2. PVC:- used in most budget priced boats.

There are several tests to check.

• If you can see the inside of the tube, through the valve, Hypalon is a dark grey or black on the inside. PVC is the same colour on both sides.
• Sand the material. Hypalon will matt down and produce a dust. PVC will just scratch, There will be no difference in colour.
• Wipe over with MEK or Acetone. Hypalon will leave an oxidization and maybe some colour on the cloth. The material will not be affected. For PVC you will have some colour on the cloth but, the surface of the material will feel tacky.

It is important to use the correct solvent on the solvent test.
