Angus Hi-Ex is a blend of high activity, synthetic foaming agents and foam stabilizers, specially formulated to produce high quality stable foam.

Hi-Ex is effective on a wide variety of Class A and Class B fire risks. The finished foam has drainage characteristics far superior to those of standard detergents; this increases its ability to carry water to the fire and acts as a positive aid to effective fire suppression.


  • Produces extremely stable long lasting foam
  • Can be used with fresh or sea water
  • Suitable for all medium and high expansion equipment
  • Economical to use
  • Three Way Fire Attack

Hi-Ex combats fires in three ways:

  1. Initial contact with fire generates a large volume of steam displacing the super heated gases and products of combustion.
  2. At the same time, the water content of the foam when converted to steam, produces a valuable cooling effect.
  3. Finally, the large volume of foam generated engulfs the area and totally seals off and extinguishes any remaining fire.
