Geoliner AL 30

The AL qualities were developed to provide a material with improved low temperature properties, improved weatherability and flexibility while maintaining chemical resistance, particularly hydrocarbons.

This was accomplished by alloying with nitrile rubber. This was building on the knowledge and experience obtained over many years of producing flashing materials.

The following are typical property tables for AL and ALR membranes.

  • high temperature aging is excellent
  • oil and grease resistance is excellent
  • good low termperature properties
  • problems - discolours in U/V and on heat, aging - therefore dark colours
The information on this page is, to the best of Kentain's knowledge, true and accurate. In some instances the temperature can exceed that specified without detrimental liner damage but may decrease the life expectancy.
