Production introduction
Available in three models - AR - AFFF 3% (-3℃), AR - AFFF 3% (-16℃), and AR - AFFF 3% (-35℃) - the Ar Afff Foam Concentrate adapts to diverse temperature conditions. All variants present as clear pale - yellow liquids, consistent with the quality of Afff Foam Liquid. Their pH levels vary by model: 7.6–7.9 for the -3℃ type, 8.0–8.3 for -16℃, and 8.5–8.7 for -35℃, ensuring chemical stability during storage and use.
Key performance features of the Ar Afff Foam Concentrate include surface tensions ranging from 16.0 to 18.1 mN/m and spreading coefficients between 4.7–7.1 mN/m, enabling rapid spread over alcohol - laden surfaces. With a viscosity of ≤2300 MPas at 20℃, the Ar Afff Foam Concentrate flows smoothly through firefighting systems. Expansion ratios (7.1±1 to 7.5±1) and 25% drainage times (10.5–15.2 min) show its ability to create a long - lasting foam blanket that smothers flames and prevents re - ignition, even in tough alcohol - fire situations.
The freezing points of -3℃, -16℃, and -35℃ let the Ar Afff Foam Concentrate be used in regions with harsh winters, where regular Afff Foam Liquid might freeze and fail. Whether in distilleries, chemical plants with alcohol - based solvents, or cold - climate industrial sites, this Ar Afff Foam Concentrate provides consistent, life - saving fire suppression for alcohol - related hazards.

Products Description
FAQ
Q: Can Ar Afff Foam Concentrate be used with any type of firefighting equipment?
A: It's compatible with most standard foam - proportioning systems. But check the equipment's specs to ensure it can handle the concentrate's viscosity (≤2300 MPas). Some older systems might need adjustments for optimal performance with this Ar Afff Foam Concentrate.
Q: How does temperature affect the foam expansion ratio of Ar Afff Foam Concentrate?
A: Lower temperatures (near the freezing point) can slightly reduce the expansion ratio. In colder conditions, the foam might be denser. Test the Ar Afff Foam Concentrate in the actual deployment environment to confirm the expansion ratio meets your needs.
Q: What's the best way to dispose of unused Ar Afff Foam Concentrate?
A: Follow local environmental regulations. Contact a hazardous - waste disposal service, as the Ar Afff Foam Concentrate contains chemicals that can't be dumped casually. Never release it into water sources or the soil.
Q: Does the Ar Afff Foam Concentrate require special training to handle?
A: Yes. Due to its specialized alcohol - resistant formula, training on proper dilution, system integration, and safe handling is recommended. Incorrect use can reduce its effectiveness against alcohol fires, so understanding its unique properties is key.
Q: Can Ar Afff Foam Concentrate be mixed with other types of fire - fighting foams?
A: Mixing with other foams is not advised, as it can disrupt the alcohol - resistant properties of the Ar Afff Foam Concentrate. Use it as a standalone solution for alcohol - based fire risks for the best results.
