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.
AFFF was developed in the 1960s under Project Light Water in a joint venture between 3M and the U.S. Navy. AFFF forms a film that floats out before the foam blanket, sealing the surface and smothering the fire by excluding oxygen. AFFF is widely used for ARFF firefighting at airports, often in conjunction with purple-K dry chemical.
