Foam Concentrates (AFFF, AR-AFFF)

-- Steady & Reliable Manufacturer --

Introduction: Suppressing Flammable Liquid Fires

Foam concentrates are specialized agents mixed with water to create an extinguishing solution, primarily used for tackling Class B fires (flammable liquids like gasoline, oil, and solvents). They work by forming an aqueous film and an insulating foam blanket, suffocating the fire and preventing reignition. We supply a full range of high-performance concentrates, notably Aqueous Film-Forming Foam (AFFF) and Alcohol-Resistant AFFF (AR-AFFF).

The quality and certification of foam concentrate are critical for environmental compliance and firefighting effectiveness. Our concentrates are manufactured to be highly stable, long-shelf-life solutions, rigorously tested to standards like UL 162 and EN 1568. We focus on environmentally improved C6-based AFFF and entirely fluorine-free foams (FFFs) as regulatory restrictions on older C8/PFAS compounds tighten.

We provide foam concentrates in standard concentrations (1%, 3%, 6%) for use in fixed systems (storage tanks, proportioners) and mobile applications (fire trucks), ensuring rapid knockdown and secure vapor sealing across all major flammable liquid hazards. (Approx. 520 words)

Advantage: Environmental Responsibility and High Performance

  • Superior Vapor Sealing: AFFF creates a thin aqueous film that rapidly seals the liquid fuel surface, preventing reignition and vapor release.
  • AR-AFFF Specialty: Our Alcohol-Resistant foam ensures a stable blanket even when applied to polar solvents which are destructive to standard AFFF.
  • Environmental Compliance: Prioritizing the latest C6-based technology and future-proofing with high-performance Fluorine-Free Foams (FFFs) to meet evolving global restrictions (PFAS/PFOA).
  • Certified Performance: Concentrates are certified to multiple global standards (UL, EN) for various hydrocarbon and polar solvent fuel types.
  • Long Shelf Life: Guaranteed long shelf life (up to 20 years if stored correctly) minimizes replacement costs for large-scale reserves.
  • Concentration Versatility: Available in 1%, 3%, and 6% concentrations, allowing optimal selection based on the specific proportioning equipment.

Application in Flammable Liquid Hazards

Petrochemical Storage Farms

Fixed foam deluge systems covering large fuel tanks and containment bunds for continuous vapor suppression and fire control.

Aircraft Hangar Foam Systems

High-expansion foam systems used to rapidly fill the volume of aircraft hangars and suppress fuel and hydraulic fluid fires.

Refineries and Process Areas

AR-AFFF used in process areas where polar solvents (alcohols, ketones) are present, which destroy standard AFFF foam blankets.

Fire Trucks and Mobile Response

3% or 6% AFFF used in the onboard foam tanks of municipal and industrial fire apparatus for immediate deployment.

Marine Vessels

IMO-certified foam concentrates used in engine rooms and cargo holds of tankers and commercial ships.

FAQ

Foam concentrates are primarily designed for Class B fires (flammable liquids). They are also effective on Class A fires (ordinary combustibles) when used as a wetting agent.

Polar solvents (e.g., alcohol, acetone) are flammable liquids that mix with water. They destroy standard AFFF foam. AR-AFFF creates a protective polymeric membrane that separates the foam blanket from the solvent, allowing it to extinguish the fire.

Older AFFF foams (C8-based) containing long-chain PFAS chemicals are being phased out globally. We focus on environmentally improved C6-based AFFF and entirely Fluorine-Free Foams (FFFs) to stay ahead of regulations.

Foam concentrate is mixed using a mechanical device called a proportioner (e.g., eductor, balanced pressure proportioner) which precisely introduces the concentrate into the water stream at the required ratio (e.g., 3:97).

This refers to the ratio of expanded foam volume to the volume of the original solution. Low expansion is 20:1 or less (used for tanks). High expansion is 200:1 to 1000:1 (used for volume filling in hangars).

NFPA requires that all stored foam concentrate be tested annually by a qualified laboratory to verify physical properties (pH, specific gravity) and firefighting performance (expansion ratio, drainage time).

You must use the concentration the proportioner is rated for. Using 6% concentrate in a 3% proportioner will result in the foam solution being too rich, wasting concentrate and potentially reducing fire performance.

If stored in the original, sealed containers and within the specified temperature range, our high-quality synthetic concentrates have a guaranteed shelf life of 10 to 20 years.

Yes, we supply complete foam system packages, including the concentrate, bladder tanks, proportioners, discharge devices, and foam makers, ensuring full system compatibility.

The most common bulk sizes are the 200-liter drum and the 1000-liter Intermediate Bulk Container (IBC) Tote, which are the most cost-effective options for large fire suppression systems.
