Heba AFFF 6% A is an aqueous film forming foam concentrate (AFFF) consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilizers. The foam forms an aqueous film that rapidly cuts off the oxygen supply and knocks-down the fire. The expanded foam form 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.
The low surface tension of the water foam concentrate solution enables the aqueous film to float on the top of the liquid surface.
Heba AFFF 6% A is be used at 6% proportioned solution (6 part concentrate in 94 parts of water) in fresh or seawater. It may also be stored as a pre mix solution in fresh water.
