Foam concentrates for Industries

Foam Agents for the Industries

Foam concentrates for industries, are placed on fire protection and associated equipment due to the risks involved. The foam extinguishing agents used here meet these strict requirements and offer excellent safety margins.

Sthamex AFFF 3% F-15 #4341

STHAMEX-AFFF 3% F-15 (#4341)
Mfg.: Dr.Sthamer – Hamburg

STHAMEX®-AFFF 3% F-15 (#4341)
STHAMEX®-AFFF 3% F-15 is a synthetic, aqueous film forming fire extinguishing foam concentrate, based on surface active agents. It is designed for use at a 3% concentration and applied with all standard low, medium, and high expansion foam equipment and fixed foam installations especially for class B fires.

Key Features:
– Oleophobic Properties: The foam is resistant to fuel contamination, making it particularly suitable for sub-surface foam applications.
– Application Versatility: On hydrocarbon-based products, it can be applied as a non-aspirated aqueous solution using equipment such as water monitors, water sprinklers, and deluge systems.

Applications:
Petrochemical industries
Airports
Onshore and offshore facilities

Limitations:
STHAMEX®-AFFF 3% F-15 (#4341) is not suitable for use on polar solvents, such as alcohols.
