High Expansion Foam (HI-EX)

High Expansion Foam (HI-EX) is a superior-quality firefighting foam concentrate designed for extinguishing and securing fires involving flammable hydrocarbon liquids, hazardous materials, and confined space fires. It is highly effective in reducing fire intensity by creating a thick, stable foam blanket that suppresses oxygen supply and prevents fire re-ignition.

HI-EX foam is formulated for use at medium and high expansion ratios, making it ideal for large enclosed spaces such as aircraft hangars, engine rooms, basements, and tunnels.

Key Features

  • Forms large volumes of stable foam for maximum fire coverage.

  • Effectively absorbs heat, reducing fire temperature.

  • Ideal for enclosed spaces where excessive water use is a concern.

  • Forms a barrier to hazardous gas emissions and prevents re-ignition.

  • Biodegradable and fluorine-free formula.
