Product Specifications

HAZGARD® 635FR meets the requirements of ULC/S668-12 Secondary Containment Liners for Aboveground Flammable and Combustible Liquid Tanks. This requirement is included in a number of Canadian Fire Codes in different jurisdictions. HAZGARD® 635FR was extensively tested and passed all the requirements for this guideline. A test report is available to show compliance with this guideline upon request. In cases where the chemical resistance of HAZGARD® 635FR to the liquid to be contained is not known, samples are available for immersion testing. Your representative can assist you in setting up a chemical test.

HAZGARD® 635FR has been tested for both chemical compatibility and permeation performance to the broad range of chemicals required by ULC S668*. This chemical testing included flammable liquids such as gasoline, gasoline mixed with alcohols, and methanol and ethanol. The testing also included combustible liquids such as diesel fuels. Additional tests have shown excellent resistance to biodiesel and biodiesel blends and heavier hydrocarbons such as lubricants. HAZGARD® 635FR is made from plastic resins that are naturally resistant to acids and bases. *Tested to meet the Class I requirements of "ULC S668 Secondary Containment Liners for Aboveground Flammable and Combustible Liquid Tanks."
