AR-AFFF Firefighting Foam Concentrate OLAS 36 – Vina Foam

GENERAL DESCRIPTION

OLAS 36 is a film-forming synthetic foam concentrate, formulated from fluorinated surfactants and hydrocarbon-based surfactants, high molecular weight polymers, and various solvents.

OLAS 36 requires relatively low energy to generate foam. The foam solution is capable of forming a film layer over most hydrocarbon fuel surfaces, as well as water-soluble polar solvents such as alcohols, acetone, etc.

This film layer separates the fuel from oxygen and prevents fuel evaporation. The water content in the foam solution also provides a cooling effect.

Suitable for use with seawater, freshwater, and hard water at mixing ratios of 3% or 6%.

• Use at 3% for Class B fires (hydrocarbon fuels)
• Use at 6% for polar solvent fires
• Excellent wetting properties also make OLAS 36 suitable for Class A fires

OLAS 36 can be used with:

• Low expansion foam equipment (foam nozzles)
• Spray devices (sprinklers, standard nozzles)
