ALCOHOL RESISTANT AFFF-AR-AFFF

Alcohol Resistant Aqueous Film Forming Foam (AR-AFFF) provide efficient vapor suppression and
extinguishment of liquid class B fires containing hydrocarbons and polar solvents.
Alcohol Resistant Aqueous Film Forming Foam (AR-AFFF) foams are required when fuels are water-miscible, such as alcohols,
acetone… Polar solvents and alcohol are able to destroy the foam blanket generated by standard class B hydrocarbon fires foams.
AR-AFFF foams are often required in high-risks facilities in the oil & gas and chemical industries such as refineries, ships, tank farms,
pharmaceutical plants and process areas.
Alcohol-Resistant Aqueous Film-Forming Foams are suitable for quick extinguishment of large-scale class B fires.
The aqueous foam would normally be destroyed very quickly on water-soluble fuels. AR-AFFF agents contain polymers,
that forms a protective film between the burning surface and the foam blanket.
This foam blanket blocks the oxygen which supply the fuel in fire,
seals the fuel surface and prevents the release of fuel vapors.
AR-AFFF film prevents foam breakdown by alcohols in the burning liquids.
The water contained in the foam solution provides a cooling effect for faster fire suppression.
AR-AFFF foams had a good burnback resistance.
