Low molecular weight polyethylene glycol (PEG) in fluorine containing fire fighting foam concentrates
11338162 · 2022-05-24 · ·

It has been discovered that low molecular weight poly(ethyleneglycol) (PEG) can be used in place of diethylene glycol monobutyl ether (DGME) in fire foam concentrates without compromising the desirable properties provided by DGME. Surprisingly it has been found that lower molecular weight PEG with a weight average molecular weight Mw of 400 or less provides comparable performance to DGME with considerably lower toxicity. Use of this PEG permits preparation of fire foam concentrates that exclude DGME completely and that are less toxic than conventional DGME-containing concentrates.
