Fire Fighting Foam Liquid
Fast fire extinguishing speed
Quickly covers the oil surface and extinguishes fires of gasoline, diesel and other hydrocarbon fuels.
Excellent film-forming and sealing performance
Forms a continuous aqueous film on oil surface, isolates oxygen, suppresses fuel vapor, and provides strong anti-reburning capability.
Good fluidity and rapid spreading
Quickly covers large-scale flowing fires with high fire control efficiency.
Compatible with dry chemical powder
Can be used together with dry powder extinguishants for better fire fighting effect.
Stable performance and long storage life
Resists high and low temperatures, low viscosity, stable mixing ratio, easy to use.
Eco-friendly
Free of PFOS, PFOA and PFAS,Low Chlorine, non-toxic, low hazard, biodegradable, compliant with EU REACH, US EPA and global environmental regulations.
Fire Fighting Foam Liquid(AFFF )is a foam concentrate based on synthetic surfactants. After being mixed with water and discharged, it forms a foam blanket to cover the burning liquid surface. At the same time, it quickly spreads and forms a continuous, sealed aqueous film on the oil surface, isolating oxygen, suppressing fuel vapor evaporation, achieving rapid fire extinguishment and long-lasting anti-reburning performance.
Core Components
Eco-friendly surfactantsProvide film-forming, foaming and spreading properties,free of persistent organic pollutants such as PFOS, PFOA and PFAS.
Foam stabilizersImprove foam stability, burn resistance and sealing performance, and extend the effective coverage time of foam.
Anti-freeze componentsWiden the applicable temperature range and ensure normal operation in low-temperature environments.
Water and co-solventsAdjust viscosity, fluidity and mixing performance to be compatible with various foam proportioning equipment.
Corrosion inhibitors and preservativesProtect storage tanks and pipeline equipment, and extend the shelf life of the product.

Frequently Asked Questions（FAQ）
Q1:What is fluorine-free foam?
Fluorine-free foam is a fire-fighting foam concentrate that does not contain any fluorinated surfactants in its formula. It is free of per- and polyfluoroalkyl substances such as PFOS, PFOA and PFAS. It is more eco-friendly and biodegradable, and complies with international environmental regulations.
Q2:Does AFFF foam contain fluorine?
Traditional AFFF (Aqueous Film Forming Foam) generally contains fluorosurfactants for rapid film forming and fire extinguishing. The environmentally friendly AFFF manufactured by Jinan Landon Fire Equipment Co., Ltd. does not contain PFOS, PFOA and PFAS substances.
Q3:What is the difference between AR AFFF and AFFF foam?
AFFF (Aqueous Film Forming Foam)It is only suitable for fires involving oil and non-water-soluble hydrocarbon fuels, such as gasoline, diesel, kerosene, etc. It cannot extinguish fires of polar solvents such as alcohol, ketones and esters.
AR-AFFF (Alcohol-Resistant Aqueous Film Forming Foam)It is a dual-purpose alcohol-resistant foam that can extinguish both oil fires and fires of water-soluble polar solvents such as alcohol, methanol and acetone. "AR" stands for alcohol-resistant.
