Hypalon vs. PVC


Comparison between Hypalon and Panatex

To ensure the higher quality of Stingray Ribs Australia we only import Hypalon Pontoon. The superior quality of Hypalon pontoons is demonstrated in the comparison below.

PROPERTIES Hypalon PVC Coated Fabric
Mechanical properties
Tear resistance Better than PVC Less than Hypalon
Resistance to abrasion Better than PVC Less than Hypalon
Low temperature resistance
Excellent Good when new but rapidly decreases with age
No porosity Reliability less than 100%
Chemical resistance
Gasoline and diesel Good Does not resist
Cleaning solvents Good Does not resist
Solvents Fair Does not resist
Greases and oils Good Fair
Tar derivatives Good Fair
Heat and UV Good Progressive evaporation of plasticizers. With age material becomes stiff and brittle.
Weather Good Good but becomes sticky and dirty.
Fading Excellent Good becomes stiffer with age.
General properties Excellent Limited
Micro-organisms and fungus Excellent Fair
Running water Good Fair
Safety of life at sea (Solas)
Approved Not Approved



There are two methods used to manufacture PVC pontoons:

  1. Glue
    • The best glue for this purpose is two part PU heat reactivated glue. The life expectancy of the glue and PVC pontoon are approx 10 years. Please note that PVC pontoons are not suitable for extreme cold or extreme hot condition like the tropics. Due to the glue being heat reactivated, glue failure in the tropics and extreme heat may occur unless steps are taken to manage pressure/heat.
  2. Heat Welding
    • The PVC is thermo welded using a special thermo welding machine.


Hypalon is a synthetic rubber and can only be glued. The glue is very specialized and unlike the glue used on PVC is not heat reactivated. The glue can withstand extreme cold and hot conditions. This is the choice of Military and Rescue organizations.
