About product

Polyfoam 3/6S AFFF-AR 3x6 %, -5°C is fire foam for extinction of hydrocarbon and polar solvent fires.

This concentrate has a pseudoplastic behaviour. It contains fluorinated and hydrocarbon surfactants to allow a good formation of an aqueous film on the surface of most hydrocarbon fuels and polar solvents, suppressing vapour leaks and preventing its contact with the oxygen and providing an excelling sealing on hot surfaces. Its formulation allows a great oil repellence, fluidity and burnback resistance.

POLYFOAM 3/6S is a perfect tool to fight fires on storage tanks, bund, process areas, loading racks, power stations, marine vessels, Onshore and offshore terminals amongst others.

POLYFOAM 3/6S dilution rate is 3% in fresh or sea water for extinguishing hydrocarbon fires and 6% for polar solvent (alcohols, ketones, ethers, esters, amines, etc.) fires or when medium expansion is required. It performs effectively on fresh or sea water and it may be proportioned with standard equipment (in-line inductors, bladder tanks, pumps, balanced pressure systems, etc.) and special purpose ones for AFFF agents (e.g. Hydrofoam nozzles).

On hydrocarbon and polar solvent fires it can be applied also with non-aspirating devices (water spray nozzles and standard sprinklers). It can be used fighting fires or covering spillages of chemicals to avoid the emission of toxic, harmful, flammable, etc., vapours, even acids. The foam has a very good resistance to all kind of chemicals. POLYFOAM 3/6S is highly biodegradable and it is manufactured according to “C6 fluorocompounds” fulfilling the 2010/2015 EPA PFOA Stewardship Program.


The concentrate should be stored at temperatures between –5° and +50°C, preferably in the original containers or in stainless steel or epoxy lined tanks. Avoid permanent contact with carbon steel, iron, cooper alloys, aluminium, etc. Do not mix with other foam concentrates without a previous verification of compatibility.


The product is supplied in 20 or 25 L PE prismatic containers, 200 L PE cylindrical drums and 1.000 L IBC containers.


Foams should neither be used in contact with electrical equipment nor with chemical products that can react with water. It is recommended to avoid the contact of the foam concentrate with the skin. In case of eye splashes wash with plenty of water. In case of ingestion do not induce vomit, drink water and take medical advice.
