In the early 1970s, National Foam, Inc. invented alcohol-resistant AFFF technology. AR-AFFF is a synthetic foam developed for both hydrocarbon and polar-solvent materials. Polar solvents are combustible liquids that destroy conventional fire-fighting foam.
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.
