Aqueous Film Forming Foam (AFFF) Concentrate

NAFFCO FILMPLUS are superior quality Aqueous Film Forming Foam concentrate which can be used to extinguish fires of non-polar hydrocarbon fuels. FILMPLUS is suitable for use with most types of proportioning and discharge equipment.

AFFF foam concentrate are designed for rapid fire knockdown by producing a thin aqueous film which helps to prevent the release of fuel vapours. The foam blanket, from which the film forming liquid drains separates oxygen from the fuel surface, extinguishes the fire and prevents re-ignition. The water content of the foam provides a cooling effect.

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.

FILMPLUS provides excellent penetrating and wetting qualities when used on Class A fires. This is important when extinguishing deep-seated fires in wood, paper, rubber and other ordinary combustibles.
