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

AFFF foam concentrate consists of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilisers. The foam forms an aqueous film that rapidly cuts off the oxygen supply and knocks down the fire. The expanded foam, from which the film is drained, forms a stable blanket that suppresses the release of flammable vapours and cools down the fuel surface extinguishing the fire and preventing re-ignition.
