MB -20

Fomtec MB -20 is a multipurpose foam concentrate consisting of a blend of hydrocarbon surfactants, solvents and stabilisers. All Fomtec multipurpose foam concentrates are totally free from fluorinated surfactants and polymers (PFAS). The fire suppression mechanism of Fomtec MB -20 is utilising the foam blankets ability to block oxygen supply to the fuel and the high water content cools the fuel surface reducing the evaporation of flammable vapours. Additionally, the foam blanket prevents reignition of an extinguished fuel surface.
