U.S. Foam l%-3% AR/AFFF (ATC/AFFF) is a versatile fire fighting foam for protection of a wide range of Class B flammable liquid hazards. U.S. Foam 1%-3% AR/AFFF (ATC/AFFF) is an all synthetic film forming foam designed for protection of water-soluble polar solvents as well as water insoluble hydrocarbon flammable liquids. When used with fresh water and foam generating equipment U.S. Foams 1%-3% AR-AFFF is transformed into a vapor blanketing foam to provide extinguishing and securing abilities.

:: Features

  • UL Approved
  • Aqueous Film Formations: U.S. Foam 1%-3% AR-AFFF, like all US Foam Aqueous Film Forming Foam (AFFF) Concentrates, has the ability to form an aqueous film which flows quickly over water-insoluble hydrocarbon fuel surfaces causing rapid fire extinguishment and vapor suppression
  • Polymeric Properties: Provides a membrane-like protective layer that forms on water-soluble polar solvants (alcohols). The foam blanket and polymeric layer remain intact. Fire suppression and vapor control are positive
  • Proportions Readily: Permits use in a wide range of proportioning equipment
  • Solution Stability: Solutions of US Foam 1%-3% AR-AFFF do not present transit time limitations through handlines or in fixed systems. US Foam concentrates undergo a program of ongoing testing to assess the impact of US Foam products on the natural environment. US Foam products are low in toxicity to tested aquatic organisms
