FLUORINE-FREE FIRE PROTECTION
Hydrocarbon Fire Protection with Fluorine-Free Foam
LANGCHAO FIRE FFF Foam Concentrate is a fluorine-free firefighting foam for hydrocarbon fuel fires involving crude oil, gasoline and fuel oils. It forms a vapor-sealing foam blanket that helps isolate oxygen, suppress flammable vapors and provide cooling for rapid fire control, while resisting burnback and reducing reignition.
Available in 3% and 6% formulations, FFF features low viscosity and Newtonian flow characteristics for use with conventional foam proportioning equipment. Freshwater and seawater formulations support applications at oil storage facilities, fuel loading racks, aircraft hangars and marine terminals. It contains no intentionally added PFAS and is not suitable for polar solvents or water-miscible fuels. Confirm fuel and equipment compatibility before use.
No intentionally added PFAS
Formulated without intentionally added fluorosurfactants, fluoropolymers, organohalogens or PFAS, according to the product datasheets.
Rapid control & burnback resistance
A spreading foam blanket helps seal the fuel surface, suppress vapor release and resist reignition.
Low-viscosity proportioning
Newtonian flow characteristics support use with conventional foam proportioning equipment.
