Our Fluorine Free Foams do not contain any fluorosurfactant, any fluoropolymer or any silicon. The rheological behavior is similar to AFFF/ARs, therefore they can be used with the same dosage systems and foam production systems as well. The results of non-aspirating devices in forceful application are not as powerful as the ones achieved by AFFF/AR. Comparing them to Newtonian Fluorine Free foams, a higher viscosity value can be seen, but with the advantage of a longer drainage time and the ability to fight polar solvent fires. They should not be mixed with AFFF/AR without studying previously their compatibility. They should not be mixed at all with AFFFs or Newtonian Fluorine Free foams.
