LS xMax

Fomtec LS xMax is a multipurpose and high expansion foam concentrate consisting of a blend of hydrocarbon surfactants, solvents and stabilisers. All Fomtec multipur-pose foam concentrates are totally free from fluorinated surfactants and polymers (PFAS). The fire suppression mechanism of Fomtec LS xMax on liquid surface fuels is utilising the foam blankets ability to block oxygen supply to the fuel and the high water content cools the fuel surface reducing the evaporation of flammable vapours. Additionally, the foam blanket prevents reignition of an extinguished fuel surface.

Application

Fomtec LS xMax is intended for use on class B hydrocarbon fuels such as oil, diesel, gasoline and aviation fuels. Fomtec LS xMax can be used with all kinds on low, medium and high ex-pansion devices. It is intended to be used at 3% proportioning. Fomtec LS xMax is also effective against class A fires such as wood, paper, textiles etc. at 0.3 to 1% proportioning. Typical applications are high expansion foam systems in ware-houses, process areas, aircraft hangars or other applications where three-dimensional fire can occur.
Suitable for mobile firefighting by use of aspirating foam discharge devices such as foam branchpipes and monitors, where application rates and technique can be adjusted to the specifics of each incident. Or in systems designed for use with the product based on recommended minimum applications rates, application duration and discharge devices.

Fire performance & Foaming

The fire performance has been measured and documented according to the “International Approvals” stated in this document. The use of the product should follow design guidelines appropriate to the type of system and application. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average low expansion 10:1, average 25% drainage time 9:00 minutes using UNI 86 test nozzle. Used in Fomtec high expansion generators the average values to the right can be expected:

High expansion, average values

Generator Expansion @ 4 bar / @ 6 bar
Fomtec Bele L - / 450:1
Fomtec Bele S 400 600:1 / 750:1
Fomtec Bele S 800 600:1 / 750:1

Storage/Shelf life

Stored in original unbroken packaging the product will have a long shelf life. Shelf life in excess of 10 years will be found in temperate climates. As with all foams, shelf life will be depen-dent on storage temperatures and conditions.
