vaPUREx®LV ICAO B 3% F-15 #7345

Low-viscosity 3 % fluorine-free fire extinguishing foam agent for efficient and effective fighting of large-scale aviation fuel fires (kerosene, Jet A, etc.).

STHAMEX®-Performance 1% F-20 #9148

Fluorine-free multi-purpose fire extinguishing foam agent for use as low, medium and high expansion foam with a 1% proportioning rate.

vaPUREx®- AR 3/3 F-5 #8342

vaPUREx® AR 3/3 is a fluorine-free alcohol resistant class B fire extinguishing foam agent for low-, medium- and high-expansion foam applications. Its special combination of polymers supports the formation of a resilient foam lamella. The generated foam displays an exceptional burnback resistance.

vaPUREx®LV ICAO C 3% F-5 #7371

Low-viscosity, newtonian fire extinguishing foam agent that achieves the highest performance level “ICAO Level C” without any additions of fluorine.

STHAMEX® 3% F-15 #9352

Fluorine-free multi-purpose fire extinguishing foam agent for use as low, medium and high expansion foam.

STHAMEX® - MARINE 3% F-20 #9372

STHAMEX® MARINE 3% F-20 is a fluorine-free fire extinguishing foam agent that has been specially developed as a replacement for fluoroprotein or AFFF foam extinguishing agents in the marine environment (e.g. for use in deck foam systems with Seawater).

STHAMEX® - IAF MARINE 2% F-10 #9271

Fluorine-free, 2 % low viscosity fire extinguishing foam agent for generation of high-expansion foam using either fire fumes or fresh air. Specially developed for use in shipping.

STHAMEX® FXS IAF 3% F-10 #2355

Fluorine-free, 3 % synthetic fire extinguishing foam agent that has been specially developed for particularly temperature and flue gas resistant high-expansion foam (Inside-Air).

STHAMEX® FXS IAF 2% F-10 #2241

Fluorine-free synthetic fire extinguishing foam agent that has been specially developed for particularly temperature and flue gas resistant high-expansion foam (Inside-Air).
