6% ARAFFF (-20°C) is a high-performance firefighting foam concentrate for Class B flammable liquid fires. It combines fast-extinguishing properties with alcohol resistance, making it effective for both hydrocarbon fuels and polar solvents.
Proportioning Rate: 3% or 6% proportioning rate, compatible with standard systems.
Alcohol-Resistant Gel Layer: Forms a stable, non-dissolving protective film on polar solvents (alcohols, ketones, esters).
Water Film Sealing: Quickly spreads a thin film over hydrocarbon fuels (gasoline, diesel, oil) to suppress vapors and prevent reignition.
Low-Temperature Performance: Operates reliably down to -20°C.
Stability: Features long foam life, strong heat resistance, and self-repairing ability.
Eco-Friendly: Formulated free of PFOS and PFOA.
Freezing Point: -20°C.
Specific Gravity: 1.02±0.1kg/L.
PH at 20°C: 6.
Expansion Ratio: 7.5.
25% Drainage Time: 12 min.
Applicable Water: Compatible with fresh water and seawater.
Storage Temperature: -15°C to 45°C.
Comparison: 6% AR-AFFF vs. Normal AFFF
| Item | 6% AR-AFFF (-20°C) | Normal AFFF |
| Application | Hydrocarbons + polar solvents | Only non-polar hydrocarbons |
| Alcohol Resistance | Forms a resistant gel film | Easily dissolves in polar solvents |
| Typical Scenarios | Chemical plants, solvent warehouses | Oil depots, gas stations |
| Formula | Alcohol-resistant polymers | Fluorocarbon / hydrocarbon surfactants |
Oil & Gas: Oil depots, refineries, airports, and terminals.
Chemical/Industrial: Chemical plants, solvent warehouses, and pharmaceutical facilities.
Mixed Hazards: Industrial sites with both hydrocarbon and polar solvent risks.
