Low Expansion Foam
Low Expansion Foam is a high-performance firefighting foam concentrate designed for controlling and extinguishing flammable liquid fires. It produces a dense, slow-draining foam blanket that effectively suppresses oxygen, cools the fire, and provides excellent vapor suppression.
LEF is suitable for a wide range of applications, including hydrocarbon and polar solvent fires, making it a preferred choice for industrial, aviation, and marine firefighting.
