AFFF foams (Aqueous Film-Forming Foam, also called A3F) contain fluoro-surfactants to efficiently extinguish and provide vapor suppression of class B hydrocarbon fuel fires such as gasoline, petroleum, benzene, kerosene, oil (water non-miscible flammable liquids). AFFF foams are mostly involved in large-scale fires in high-risks industries: refineries, offshore platforms and airports.
USAFE’s GREEN AFFF produces high-quality foam blanket on the fuel surface by forming an aqueous film which forms a fuel vapor barrier. The foam blanket blocks oxygen which supplies to the burning fuel and quickly flows over the flammable liquids to form an aqueous film and seal the fuel surface while suppressing fuel vapors.
The foam blanket has a cooling effect to rapidly extinguish fires. USAFE AFFF foams have fast fire knockdown and long burn back resistance characteristics.
AFFF can be used at Low, Medium and High Expansion, also used in gentle and forceful applications. USAFE fire suppression agents can be used with a wide range of firefighting equipment. USAFE high performance synthetic foams are made as per the national and international standards like Bureau of Indian Standards (ISI), EN1568, UL, NFPA, IMO…Foam concentrates are also available in AR-AFFF for water-miscible fuels in fire.
USAFE high performances AFFF are produced using modern C6 fluoro-surfactants, which are considered safer and have less impact on the environment due to their short-chain. USAFE firefighting foams do not contain PFOS (Perfluorooctyl Sulfonate, also named C8) and PFOA (Perfluorooctanoic Acid). The use of PFOS & PFOA is now restricted due to their impact on the environment and health.
