Fire extinguishing foam concentrate NFF-331

SKUM NFF-331 3%x3% Non-Fluorinated Foam Concentrate is a 3x3 alcohol-resistant non-fluorinated foam concentrate that provides superior fire and vapor suppression for Class B, polar solvent, and hydrocarbon fuel fires. This concentrate proportions in a wide range of equipment including in-line eductors and balanced pressure systems using bladder tanks or foam pumps and is suitable for sprinkler systems and various applications using standard discharge devices. SKUM NFF-331 foam is intended for forceful or gentle firefighting applications at 3% solution on hydrocarbon fuels and at 3% solution on polar solvent fuels in fresh, salt, hard, and brackish water. SKUM NFF-331 foam concentrate utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance: The foam blanket has extended drain times to help block oxygen to the fuel and suppress fuel vapor On polar solvent fires, liquid drains from the foam blanket and forms a polymeric membrane which suppresses vapors and seals the fuel surface The water content of the foam solution produces a cooling effect for additional fire suppression SKUM NFF-331 foam concentrate is a non-Newtonian fluid that is both pseudoplastic and thixotropic. Due to these properties, dynamic viscosity will decrease as shear increases. SKUM NFF-331 foam concentrate is a non-fluorinated firefighting foam concentrate, meaning it does not have any intentionally added PFAS chemistry and is produced in equipment that has not handled PFAS chemistry. SKUM NFF-331 concentrate thus complies with directives (EU) 2017/1000 on PFOA and 2019/1021 (EU POPs directive).
