Class A Foam

DESCRIPTION

NAFFCO Class A Foam is an non-corrosive, non-toxic, biodegradable Class A fire fighting foam concentrate. When mixed with water in the correct proportion, it changes the properties of water; it reduces the surface tension of the water, and produces foam which allows the water to cling to vertical or horizontal surfaces without run off. This allows the water to absorb more heat and provides greater penetration into Class A fuels.

Aqueous Film Forming Foam (AFFF) Concentrate

DESCRIPTION

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.

Alcohol Resistant Aqueous Film Forming Foam (AR-AFFF) Concentrate

DESCRIPTION

FILMPLUS AR is a new generation of Alcohol Resistant Aqueous Film Forming Foam Concentrate based on C6 fluorosurfactants which are safer to the environment when fighting hydrocarbon and polar solvent fires.

The film forming characteristics of FILMPLUS AR means that it spreads rapidly across a fire. As a result, it is highly effective against hydrocarbon fires and with the addition of special polymers it is also highly effective against polar solvents. When used in an emergency, it generates a free flowing cohesive foam blanket with excellent burn back resistance.
