Fluoroprotein foam has fast knockdown characteristics and it can also be used together with dry chemicals that destroy protein foam. In the mid-1960s, the US Navy developed aqueous film-forming foam (AFFF). This synthetic foam has a low viscosity and spreads rapidly across the surface of most hydrocarbon fuels. A water film forms beneath the ...
Immediately after 3M chose to no longer manufacture PFOS in 2000, the company deployed Schaefer to develop a replacement for the Aqueous Film Forming Foams (AFFF). By 2002, Shaefer, who had worked for years on "foams used to put out forest fires", developed a fluorine-free foam that was able to put out jet fuel fires within 46 seconds.
Firefighters using aqueous film forming foam (AFFF) PFASs are commonly used in Class B firefighting foams due to their hydrophobic and lipophobic properties, as well as the stability of the chemicals when exposed to high heat. [222]
PFOS, together with PFOA, has also been used to make aqueous film forming foam (AFFF), a component of fire-fighting foams, and alcohol-type concentrate foams. PFOS compounds can also be found in some impregnation agents for textiles, paper, and leather; in wax, polishes, paints, varnishes, and cleaning products for general use; in metal ...
Then in the 1960's, the US navy and 3M created a new type of fire-fighting foam using PFAS chemicals, "aqueous film-forming foam" or AFFF, which was then shipped around the world and used at airports, military sites, and fire-fighting training centers. The chemicals are now used in many household products including nail polish, makeup, shampoos ...
