Alcohol Resistant AFFF Foam

Delta's range of Alcohol-Resistant Aqueous Film Forming Foam, more commonly referred to as AR-AFFF,  includes a number of options in 1% x 1%, 1% x 3%, 3% x 3% and 3% x 6% variants.

The main advantage of AR-AFFF is in it's effectiveness in fire and vapour suppression of Class B, Polar Solvent and  Hydrocarbon fires. The low surface tension of the water/foam concentrate solution enables the aqueous film, which is heavier than the burning liquid, to float on top of the hydrocarbon liquid surface. When applied on polar solvents a polymeric membrane makes it possible for the foam blanket to extinguish effectively.
