AR-AFFF exhibits the best cross-functional performance for flame aff, burnback resistance, extended vapor suppression, manufacturing and proportioning consistency, and the longest potential shelf life. While early alcohol-resistant foams were based on mixtures of protein foams and chemicals called metal soaps, the most current alcohol-resistant concentrates are based on AFFF concentrates to which a water soluble polymer polysaccharide has been added.
AR-AFFF Foam Concentrates
When these foam agents are applied to a water soluble fuel such as methyl alcohol, a polymeric membrane is formed between the foam and the water soluble fuel. You may be trying to access this site from a secured browser on the server.

There are three fire extinguishing mechanisms in effect when using the concentrates on either a conventional Class B hydrocarbon fuel such as gasoline or diesel fuel, or a Class B polar solvent water miscible fuel such as methanol or acetone. An aqueous film is formed in the case of a conventional hydrocarbon fuel, or a polymeric membrane in the case of a polar solvent fuel.
This film or membrane forms a barrier to help prevent the release of fuel vapor. Regardless of the fuel type, a foam blanket is formed which excludes oxygen and from which drains the liquids that form the film or the polymeric membrane.
The water content of the foam provides a cooling effect. Typical applications include oil and gas facilities, chemical plants, refineries and tank farms, alternative fuel facilities, afrf, municipal fire service, and many others. Because of the low energy required to make foam, they can be used with both aspirating and non-aspirating discharge devices.
To provide even greater fire protection capability, both agents may be used with dry chemical extinguishing agents without regard to the order of application. However, with the velocity of the dry chemical discharge, care must be taken not to submerge the polymeric membrane below the fuel surface when using the twin agent method on polar solvent fuels.
Water hardness should not exceed ppm expressed as calcium and magnesium. They may also be used and stored as a pre-mixed solution in only fresh, potable water. They contain no PFOS. The foam concentrate has a dramatically reduced viscosity that enhances performance in all types of foam proportioning equipment including inline eductors, balanced pressure systems, and built-in systems aboard CFR vehicles.
To provide even greater fire protection capability, it may be used with dry chemical extinguishing agents without regard to the order of application.
