High-Expansion Foam Concentrates

SKUM High-Expansion (Hi-Ex) concentrates produce flexible firefighting foams used in fighting both indoor and outdoor Class A, Class B, and LNG fires. Expansion ratios from 50:1 up to 1000:1 make these foams suitable for fire suppression in a variety of applications including aircraft hangars, flammable liquid storage areas, and LNG facilities.

Our Hi-Ex concentrates can quickly form substantial volumes of foam for large-capacity applications in fire and vapour suppression. When used in conjunction with SKUM high-expansion generators, HOTFOAM Hi-Ex concentrate is capable of totally flooding over-sized rooms and enclosures for effective suppression of horizontal and vertical (three-dimensional) fires with minimal water usage. Hi-Ex foam is often used to suppress fires in large buildings containing high value property such as aircraft hangars and distribution warehouses.
