High Expansion Foam

High Expansion Foam is a superior quality synthetic foam concentrate used at 2% concentration for extinguishing fires where total flooding application is desired. High expansion foam effects extinguishment in two ways: total flooding of the involved area limits the amount of oxygen required to support free combustion and provides a slow continuous release of foam solution for cooling and penetration.

High Expansion Foam is a low energy foaming agent, and although designed for use with high expansion equipment, it can be used in both air-aspirating and non-air aspirating foam making devices. The special surface active agents in High Expansion Foam concentrate give the foam the ability to drain very slowly when used with high expansion generators. This gives the finished foam the ability to travel long distances and retain water to provide effective fire fighting capabilities.

Applications:

High Expansion Foam is suitable for use in combating fires in buildings, process areas, warehouses, aircraft hangar systems, or anywhere total flooding is desired. High Expansion Foam systems can be used for protection of LNG storage areas where it quickly blankets the flammable liquid surface and helps control vapor release. High Expansion Foam is also useful as a wetting agent in combating Class A fires. Although developed for use in high expansion foam generating equipment, NF High Expansion Foam can be used in both medium and low expansion foam equipment. Medium expansion foam is particularly effective for vapor suppression applications.
