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.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.
