AFFF Firefighting Foam Concentrate OLAS 1 – Vina Foam

PRODUCT DESCRIPTION

OLAS 1 is an AFFF (Aqueous Film Forming Foam) firefighting foam concentrate, formulated from a blend of fluorinated surfactants, hydrocarbon-based surfactants, along with solvents and performance-enhancing additives.

OLAS 1 requires relatively low energy to generate foam. The resulting foam solution forms an aqueous film over most hydrocarbon fuel surfaces. This film separates the fuel from oxygen and prevents fuel evaporation. Additionally, the water content in the foam provides a cooling effect.

OLAS 1 is suitable for use with seawater, freshwater, and brackish water at a mixing ratio of 1%. The foam solution can also be stored and used in firefighting systems.
