There are two foam categories:

1. Those for use on flammable hydrocarbon fuels, such as gasoline, diesel, kerosene, jet fuel, etc, which don’t mix with water (float on top);
2. Water additives for use on polar solvent or alcohol type fuels,which mix readily with water.

CENTA's Elinex AFFF (Aqueous Film Forming Foam) provides a film barrier that prevents the fire from spreading. CENTA Fire Fighting Foams do not contain Fluoroprotein (FP) which is ineffective against hydrocarbon fires. These brief videos illustrate the difference between AFF and Fluoroprotein (FP) foam or water.

The difference between CENTA’S Aqueous Film Forming Foam (AFFF) vsFluoroprotein (FP) Foams

Aqueous Film Forming Foam (AFFF)

1. Foam is sprayed on the fire
2. Foam controls the oxygen
3. A film forms beneath the foam and covers the flammable liquid
4. The film cools the combustable fuel, and isolates the liquid from gas
5. Film stops the formation of flammable vapor, controls heat and burn back
6. Foam drains into the film
7. Water cools the liquid
