STHAMEX-Performance 1% F-20 is a fluorine-free multi-purpose fire extinguishing foam agent for use as low, medium and high expansion foam applications at 1% fresh and sea water. Used in lower concentrations, this fully biodegradable foam agent is an ideal wetting agent for solid, vegetation and forest fires. Its excellent foaming properties and overall performance make it particularly suitable for use by municipal fire departments. It also has ICAO B approval for use on airports and helidecks. Thanks to its high frost resistance STHAMEX-Performance 1% F-20 can be used down to -20°C without any problems.

vaPUREx AR 3/3 F-5 is a fluorine-free, alcohol-resistant Class B foam extinguishing agent designed for use as heavy, medium, and light foam at a 3% admixture with fresh or seawater. This foam agent is highly effective for both non-polar (not water-miscible) and polar (water-miscible) fuels. Its rapid and efficient extinguishing performance, combined with a highly stable foam blanket, makes the agent exceptionally robust and powerful. Thanks to various certifications and tests such as LASTFIRE, ICAO B, IMO, and others, the foam agent can be used across a wide range of applications.

vaPUREx LV ICAO C 3% F-5 is a low-viscosity, Newtonian foam concentrate with the highest performance level according to the ICAO standard: "ICAO Level C." Manufactured without the addition of fluorine compounds, it is the perfect, future-proof foam agent for airports, helidecks, terminals, and baggage carousels. vaPUREx LV ICAO C 3% F-5 is compatible with all commercially available proportioners and, due to its properties, can be used with existing technology. This eliminates the need to invest in new equipment.

STHAMEX- 3% is a fluorine-free multipurpose fire extinguishing foam agent for use as low-, medium- and high-expansion foam. Used at low concentrations the completely biodegradable foam concentrate is a excellent wetting agent for class-A fires including forest and vegetation fires. STHAMEX multipurpose foam concentrates are universally applicable and produce a robust foam cover. These easy-to-use products are particularly suitable for municipal fire services.

STHAMEX-Performance 1% F-10 is a fluorine-free multi-purpose fire extinguishing foam agent for low-, medium- and high-expansion foam applications at 1% proportioning rate. Used at lower concentrations, this fully biodegradable foam agent is an ideal wetting agent for class A and wild fires. Due to its excellent foaming properties, this product proves particularly suitable for municipal fire services.

STHAMEX - MARINE 3% F-20 is a fluorine-free fire extinguishing foam agent specially developed as a replacement for fluoroprotein or AFFF fire extinguishing foam agents in the marine environment (e.g. for use in deck foam systems). The product was developed for fighting fires of non-polar liquids with low- and high-expansion foam in the marine environment (tankers, drilling rigs, ....) in accordance with IMO MSC.1/Circ. 1312 and ICAO Level B with seawater. The low viscosity allows the use of commercially available proportioners and dosing systems down to the lowest operating temperature of -20°C. These properties of STHAMEX - MARINE 3% F-20 make it particularly easy to replace newtonian and fluorine-containing foam concentrates. This makes STHAMEX - MARINE 3% F-20 the fluorine-free alternative for fluoroprotein or AFFF foaming agents on board ships, off-shore platforms, etc.

vaPUREx AR 1/3 F-5 is readily biodegradable, fluorine- and preservatives-free. The generated foam has an unusually high water-binding capacity and special viscoelastic properties, which significantly determine the performance profile: the foam is very flowable, seals well and is particularly stable against heat and air movement. Minor damage to the foam blanket (e.g. caused by falling objects) closes automatically, thus ensuring a high level of safety against re-ignition. vaPUREx  AR 1/3 F-5 is resistant to both polar and non-polar, foam-destroying hydrocarbons and mixtures thereof. A stable polymer film forms on polar, foam-destroying liquid hydrocarbons, which prevents further destruction of the foam.

TRAINING FOAM-N 3% F-0 is an environmentally friendly, fluorine-free and very fluid (Newtonian) training foam concentrate composed of readily and fully bio-degradable, surface-active ingredients especially designed for the purpose of training firemen on the use and application of firefighting foams. The easily degradable ingredients make the all-important hands-on practice with foam particularly environmentally friendly.
