ANSUL® NFF-331 3%x3% Non-Fluorinated AR-SFFF Alcohol-Resistant Foam Concentrate, 55 gallon (208 liter) drum

ANSUL® NFF-331 3%x3% is an alcohol-resistant synthetic fluorine-free foam (AR-SFFF) concentrate that provides superior fire and vapor suppression performance for hydrocarbon fuels with low water solubility such as crude oils, gasolines, diesel fuels, and aviation fuels as well as polar solvent fuels with appreciable water solubility such as methyl and ethyl alcohol, isopropyl alcohol, acetone, esters, and methyl ethyl ketone.  It is designed for use as a 3% solution on hydrocarbon fuels and at 3% solution on polar solvent fuels in fresh, salt, hard, and brackish water using standard discharge devices. It can also combat Class A fires and can be used in conjunction with dry chemical agents to provide even greater fire suppression performance. 

ANSUL® NFF-331 foam concentrate does not have any intentionally added PFAS (perfluoroalkyl substances) and is produced in equipment that has not handled PFAS chemistry. This concentrate thus complies with directives (EU) 2017/1000 on PFOA (perfluorooctanoic acid) and 2019/1021 (EU POPs directive). ANSUL® NFF-331 foam concentrate has been subjected to OECD 301F testing and after 28 days is considered readily biodegradable.

Typical applications for ANSUL® NFF-331 3%x3% include industrial chemical and petroleum processing facilities, fuel or chemical storage tanks, truck or rail loading and unloading facilities, flammable liquid containment areas and warehouse/storage facilities, aircraft hangars, and mobile equipment.
