The CHEMGUARD brand 6% Fluoroprotein Foam Concentrate, CP2605, is formulated from hydrolyzed protein, fluorochemical surfactants, foam stabilizers (metal salts), bactericide, corrosion inhibitors, freezing point depressants and solvents. It is transported and stored as a concentrate to provide ease of use and considerable savings in weight and space.
Once the fire extinction has been achieved the high stability of the foam blanket ensures against the risk of reignition and provides excellent protection against burn back should any inaccessible pockets of fire remain.
Two fire extinguishing mechanisms are in effect when using fluoroprotein foams. First, a foam blanket prevents the release of fuel vapor. Second, the water content of the foam provides a cooling effect.
