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|
|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%|
|Gasoline and diesel||Good||Does not resist|
|Cleaning solvents||Good||Does not resist|
|Solvents||Fair||Does not resist|
|Greases and oils||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.|
|Micro-organisms and fungus||Excellent||Fair|
|Safety of life at sea (Solas)|
There are two methods used to manufacture PVC pontoons:
- 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.
- 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.
