Formulated using a newly patented and proprietary technology. The foam concentrate has a dramatically reduced viscosity as compared to other listed polar-solvent type AR-AFFF concentrates on the market. This reduced viscosity enhances performance in all types of foam proportioning equipment including inline eductors, balanced pressure systems, and built-in systems aboard CFR vehicles. Superior to other 3% foam concentrates, this includes the blended gasoline additive Methyl Tertiary Butyl Ether (MTBE) which is being used worldwide as an oxygenate to make gasoline cleaner burning. 



Three fire extinguishing mechanisms in effect when using ANSULITE 3x3 Low-Viscosity AR-AFFF Concentrate on either a conventional Class B hydrocarbon fuel such as gasoline, diesel fuel, etc., or a Class B polar solvent (water miscible fuel) such as methyl alcohol, acetone, etc. First, 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. Second, 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. Third, the water content of the foam produces a cooling effect.
