The UL Listed high expansion foam systems protect applications requiring fast and optimal fire suppression, such as aircraft hangars, with fluorine free concentrate consisting of hydrocarbon surfactants blended with various solvents, preservatives and stabilizers. The concentrate is free from fluorine surfactants and has been primarily designed for flammable liquid protection in high expansion systems. 3% XMAX foam concentrate should be used at 3% of the solution volume (3 parts concentrate in 97 parts of water) in brackish, fresh or seawater.
