3% AFFF Foam Concentrate 1000L Fire Fighting AFFF Foam Concentrate

3% AFFF 1000L Pack Aqueous Film-Forming Foam Concentrate is a highly efficient firefighting agent specifically designed for hydrocarbon fires. With its large packaging catering to industrial-grade needs, it serves as a critical fire barrier in sectors such as petroleum, chemical, and transportation, thanks to its rapid film-forming capability, strong resistance to re-ignition, and broad applicability. Strict adherence to mixing ratios and operational guidelines is essential to maximize its fire-extinguishing effectiveness.

Product Details

Product Formation

3% AFFF (Aqueous Film-Forming Foam Extinguishing Agent) is an efficient and multi-purpose fire-fighting foam concentrate, specifically designed to extinguish Class B fires (flammable liquid fires, such as hydrocarbon fuels like gasoline, diesel, crude oil, kerosene, etc.) and some Class A fires (solid material fires). The "3%" indicates that the mixing ratio of the foam concentrate to water is 3:97 (i.e., 3 parts of concentrate + 97 parts of water), which is a low-concentration ratio, balancing economy and fire-extinguishing efficiency; "1000L" refers to the product's packaging capacity of 1000 liters (usually in large storage barrels or tanks), suitable for industrial-grade and large-scale fire-fighting needs.

When the foam comes into contact with the surface of the burning liquid, it quickly spreads out to form a dense aqueous film (lightweight water film) and a foam layer. The water film isolates the fuel from oxygen and accelerates cooling, while the foam layer inhibits the volatilization of vapor. The dual effects achieve rapid fire control; at the same time, the foam has strong stability, which can effectively prevent re-ignition.

Product Features

The product features "3% low concentration ratio + AFFF aqueous film-forming technology + 1000L large packaging" as its core labels, and is specially designed for efficient fire fighting. Its characteristics are as follows:

Low consumption and high return: 3% is the mixing ratio of foam concentrate to water (3:97), which is much lower than some high-concentration foams (such as 6% type). In the same fire-fighting scenario, the dosage of concentrate is reduced by 50%, significantly lowering the long-term storage and supply costs.
Strong adaptability: The low-concentration design is compatible with most conventional fire water supply systems (such as municipal pipe networks, fire pools), and can achieve effective mixing without additional pressurization equipment.
Aqueous film isolates oxygen: When the foam comes into contact with hydrocarbon fuels (gasoline, diesel, etc.), it instantly forms a nanoscale "aqueous film" on the water surface, physically isolating the fuel from the air, blocking the combustion chain reaction, and achieving second-level fire control.
Double protection of foam layer: The dense foam layer covers the liquid surface, inhibiting steam volatilization, and together with the cooling effect of the water film, the dual mechanism ensures strong anti-reignition performance (especially for flowing fires and pool fires).
Fast spreading: The foam has low surface tension and can quickly spread on inclined or undulating liquid surfaces (such as oil tank floating roofs, ship decks), covering the fire source without dead corners.
Wide coverage of fire types: It mainly targets Class B hydrocarbon fires (oil, petrochemical products, fuel leaks), and assists in dealing with Class A solid fires (such as wood, paper). Some formulations are compatible with polar solvent (methanol, ethanol) fires (specific models need to be confirmed).
Strong scene adaptability: It can be used in fixed fire extinguishing systems (foam generators in storage tank areas, dock fire pipe networks) and can also be matched with mobile equipment (fire truck foam cannons, foam guns) to meet the needs of various fields such as industry, transportation, and public facilities.

Product Parameter

Parameter Item	Typical Value/Range
Product Name	3% AFFF Water Film Forming Foam Concentrate
Mixing Ratio	3% (±0.5%), i.e., 3L concentrate + 97L water
Foam Expansion Ratio	5~10 times (foam volume/solution volume)
Storage Temperature	Recommended 0~40℃; short - term tolerance -20~50℃
Storage Humidity	≤80% RH (Relative Humidity)
Toxicity	Acute oral toxicity LD₅₀ > 5000 mg/kg (low toxicity, belongs to the practically non - toxic category)
Applicable Fire Pump Materials	Stainless steel, copper, aluminum alloy
Scenario Adaptation	- Low - temperature environment: Use directly at temperatures above - 10℃; for the range of - 10~-20℃, add 10%~15% ethylene glycol antifreeze (the mixed solution still maintains a 3% effective concentration);
	- High - altitude areas: When the altitude exceeds 3000m, the mixing ratio remains unchanged; verify the fire pump head (due to low atmospheric pressure, water suction capacity decreases);
	- Seawater compatibility: Can directly mix with seawater (salinity ≤3.5%); however, fresh water is recommended for long - term use (to reduce equipment corrosion).
