Technical Data

UV Resistance

The following test was conducted to compare the Air-Dock material (X-DOCK made from Dupont Elvaloy®) to a sample of Hypalon. Elvaloy and Hypalon are both used on higher grade inflatable boats. Elvaloy has also been used on inflatable oil spill booms, membrane building roofs, chemical tanks covers, and pond liners for over twenty years and on inflatable boats for about five years. Hypalon has been used on inflatable boats for over twenty years because of it's durability and resistance to UV sunlight. Some of those original Hypolon boats are still in use. The following test shows how the Elvaloy (Air-Dock) material holds up to sunlight compared to Hypalon. Another material commonly used on less expensive inflatable boats is vinyl (known as PVC or polyvinylchloride). These boats do not hold up well in the sunlight because vinyl has oil-based plasticizers which migrate out of the material after prolonged exposure to UV sunlight leaving the material dry and brittle.

Determination: The test has been discontinued due to the premature failure of the Hypalon to simulated outdoor exposure.

Abrasion Resistance

The next test was conducted to compare X-DOCK to Hypalon in abrasion resistance. You have probably seen Hypalon boats used for whitewater rafting where the boats often strike rocks and logs.

Chemical Resistance

The data below is the result of laboratory tests and is intended to serve only as a guide. No performance warranty is intended or implied. The degree of chemical attack on any material is governed by the conditions under which it is exposed. Exposure time, temperature and size of the areas of exposure usually varies considerably in application, therefore, this table is given and accepted at the user's risk. Confirmation of the validity and suitability in specific cases should be obtained.

RATING KEY:

B - Fluid has minor to moderate effect

C - Fluid had severe effect
