Aberdeen Foam 2% HI-EX
2% High Expansion Foam (HI-EX)
A versatile, high quality High Expansion Foam concentrate for use with both medium and high expansion foam equipment using potable (fresh) water or seawater.
Used at a concentration of 2%, Aberdeen 2% HI-EX produces very stable foams for control of Class A and Class B fires in confined spaces.
Quickly extinguishes and secures Class A fires of material such as paper, wood and tyres and Class B hydrocarbon fires of liquids such as crude oil, gasoline, aviation kerosene and fuel oil.

With medium expansion foam equipment, Aberdeen Foam 2% HI-EX offers advantages over Low Expansion Foams in the control of cryogenic flammable liquid fires or as a vapour suppression foam on toxic liquid spills.
Formulated for use with either fresh or seawater.
Suitable for use in both tropical and cold climates, with maximum and minimum storage and use temperatures of 50°C and -10°C.
Not suitable for use on fuels which are polar solvents and water miscible such as alcohols, ketones, aldehydes and ethers, or for the control of pooled liquid fires in the open.
Also suitable for use for training purposes.
Proportioning Information
