AFFF Foam Concentrate
AFFF Foam Concentrate is a superior quality and environmentally responsible aqueous film forming foam (AFFF) which is used at 1%, 3% or 6% concentration to extinguish fires in hydrocarbon fuels. AFFF foam concentrates are designed for rapid fire knockdown by producing a thin aqueous film which spreads across the surface of the fuel, separating the fuel from oxygen. This is accomplished by allowing the foam solution to quickly drain from the foam bubble, which in turn affects long term sealability and burnback resistance.
The aqueous film is produced by the fluorocarbon surfactant, reducing the surface tension of the foam solution to a point where the solution can be supported by the surface tension of the fuel. The effectiveness of the aqueous film is directly influenced by the surface tension of the fuel. The film tends to be more effective on fuels with higher surface tension, such as diesel and jet fuels, and less effective on fuels with lower surface tension such as hexane and gasoline.
AFFF is used in fire suppression systems and manually to fight fires involving hydrocarbon fuels such as crude oil, gasoline, and fuel oils. It is not suitable for use on polar solvents or water miscible fuels such as alcohols, ketones, esters, and ethers. Typical installations include foam water sprinkler systems, aircraft hangars, loading racks, process areas, etc. AFFF 3% is an excellent agent for use in aircraft rescue and fire fighting (ARFF) or other manual fire fighting applications where polar solvent fuels are not encountered. It is also useful as a wetting agent in combating Class A fires.
