STHAMEX -  AFFF
is designed for generating low and medium expansion foam and owing to its high foam density long throwing distances are achieved.
STHAMEX-AFFF forms foam very readily and is therefore also suitable for use as medium expansion foam and in foam/water sprinkler systems. The high water releasing capacity favours film formation, increases flowability,  reduces the extinction time and cools the source of fire. The aqueous film extinguishes fires even in areas not yet reached by the foam and prevents reignition should the foam blanket get ruptured. The foam is oil-repellent (oleophobic), i.e. it does not load itself with petroleum products and is,  therefore ideal for sub-surface foam application.
 

STHAMEX /  STHAMEX - K / STHAMEX - SV
STHAMEX / STHAMEX-K is suitable for  generating low, medium and high expansion foam used for extinguishing fires of  class A + B, and - as a precaution -  can also be used to suppress emissions of spilled liquids where small amounts of gas can escape. STHAMEXreduces the surface tension of water and thus is an excellent wetting agent, as well. The  flowable foam extinguishes safely and forms a gastight cover on combustible surfaces, is resistant to heat radiation, gas and wind, thus considerably reducing the risk of re-ignition.
 

STHAMEX -  class A
Faster than usual foam concentrates  STHAMEX- class-Apenetrates the surface of combustible solids resulting in extraordinary cooling and extinguishing effectiveness. CAFS application  intensifies the wetting and extinguishing effect. The compressed air used with this application method characterises the foam properties. The foam bubbles are  particularly small and stable for long lasting adherence of the foam to solids. The foam solution drains slowly and steadily onto the combustible surface which at the same time is being sheltered from heat radiation. Thus the foam solution  continuously penetrates the burning material and permanently wets its surface without draining instantly as it would be the case if only water was used. The  cooling effect by constant evaporation of the extinguishing agent is being improved. The efficiency of the extinguishing agent used is increased by the multiple: compared to water the effectiveness of extinguishing agent is raised by 7 - 8 times. When STHAMEX-class-A is used inside buildings the damage caused by water can be reduced considerably.
