Production introduction
Available in three temperature-adaptive models-AR-AFFF 6% (-3℃), AR-AFFF 6% (-16℃), and AR-AFFF 6% (-35℃)-the concentrate ensures reliability across extreme climates. All variants maintain a clear pale yellow liquid appearance, with pH levels optimized for stability: 7.4–7.5 (for -3℃), 7.9–8.5 (for -16℃), and 6.9–7.1 (for -35℃). These formulations resist chemical degradation during storage, a hallmark of the AR-AFFF 6% Foam Concentrate's quality.
Key performance metrics distinguish this product: Surface tensions range from 15.9 mN/m (lowest temp) to 18.1 mN/m (extreme cold), enabling rapid fuel-surface coverage. Spreading coefficients (4.5–6.5 mN/m) ensure the foam blankets irregular containers, while a viscosity ≤2300 MPas at 20℃ guarantees smooth flow through hoses. Expansion ratios (6.4±1 to 7.5±1) and 25% drainage times (9.8–16.1 min) produce a persistent foam layer that suppresses combustion and shields against heat relapse.
Freezing points of -3℃, -16℃, and -35℃ allow deployment in severe winter regions, where conventional foams might solidify. Whether combating tank fires or solvent spills, the AR-AFFF 6% Foam Concentrate delivers precision suppression. Its temperature flexibility, optimized flow, and alcohol-resistant film make it indispensable for fire safety systems, safeguarding assets and lives in challenging alcohol-fire scenarios.

Products Description
FAQ
Q: How does the AR-AFFF 6% Foam Concentrate perform in high-altitude environments?
A: At high altitudes, lower atmospheric pressure slightly reduces foam expansion. However, the concentrate's formulation maintains core performance-test in situ to confirm expansion ratios and adjust water pressure if needed.
Q: Can the AR-AFFF 6% Foam Concentrate be mixed with non-alcohol-resistant foams?
A: Mixing is not recommended, as it disrupts the alcohol-resistant film. Use this AR-AFFF 6% Foam Concentrate as a standalone solution for alcohol-fueled fires to ensure maximum efficacy.
Q: What is the shelf life of AR-AFFF 6% Foam Concentrate under optimal storage?
A: When stored in sealed containers at 5–30℃ (away from direct sunlight), the concentrate remains effective for 8–10 years. Regularly inspect for color changes or sediment to verify quality.
Q: What precautions are needed when transporting 3% AR-AFF Foam 20 Ltr in vehicles?
A: Set proportioners to 6% concentrate-to-water ratio. Use a flow meter to verify mixture accuracy, as incorrect ratios reduce the alcohol-resistant film's durability.
Q: Does the AR-AFFF 6% Foam Concentrate require specialized equipment for application?
A: It works with most standard foam-delivery systems (e.g., fixed systems, portable monitors). However, ensure equipment can handle the concentrate's viscosity (≤2300 MPas) for consistent performance.
