U.S. FOAM 3%-3% AR-AFFF is a versatile fire fighting foam for protection of a wide range of Class B flammable liquid hazards. U.S. Foam 3% or 3% AR-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. Foam 3% or 3% AR-AFFF is transfomed into a vapor-blanketing foam to provide extinguishing and securing abilities.

:: Features

  • UL Approved
  • Aqueous Film Formation: U.S. Foam 3% or 3% AR-AFFF, like all U.S. 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 solvents (alcohols). The foam blanket and polymeric layer remain intact. Fire suppression and vapor control are positive
  • Proportions Readily: Permits use in a wide range or proportioning equipment
  • Solution Stability: Solutions of U.S. Foam 3% or 3% AR-AFFF do not present transit time limitations through handlines or in fixed systems
