Aqueous film-forming foam concentrates (AFFF)

comprises a range of synthetic, aqueous film-forming foam (AFFF) concentrates, which are designed for very fast and lasting fire extinguishing results with high burn-back resistance. These advantages are apparent particularly when extinguishing large-scale liquid fires. AFFF foams form a self-sealing duplex aqueous film on non-polar hydrocarbons, which also allows for application in non-aspirated form.
