Production introduction
Available in three models-AFFF 6% (-1°C), AFFF 6% (-16°C), and AFFF 6% (-35°C)-the Afff Foam Liquid ensures reliable performance in varying temperature conditions. All variants appear as clear pale - yellow liquids, with pH levels optimized for stability: 8.3–8.8 for the -1°C model, 7.4–7.7 for -16°C, and 8.5–8.7 for -35°C. These pH ranges ensure compatibility with firefighting systems and long - term storage resilience.
Key performance attributes of the Afff Foam Liquid include low surface tension (16.2–18.1 mN/m) and controlled spreading coefficients (4.7–6.5 mN/m), enabling swift foam spread over fuel surfaces. With a viscosity of ≤20 MPas at 20°C, the Afff Foam Liquid flows smoothly through hoses and nozzles. Expansion ratios (6.6±1 to 7.9±1) and 25% drainage times (3.1–3.4 min) guarantee durable foam blankets that smother fires effectively.
The freezing points of -1°C, -16°C, and -35°C allow the Afff Foam Liquid to deploy in regions with severe winters, where conventional foams might fail. Whether used in refineries, storage terminals, or cold - climate operations, this Afff Foam Liquid delivers consistent, life - saving fire suppression.

Products Description
FAQ
Q: How to select the right Afff Foam Liquid model for my location's winter temperatures?
A: Choose based on the lowest expected winter temperature. Use AFFF 6% (-1°C) for mild climates (no sustained sub - zero temps), AFFF 6% (-16°C) for colder regions, and AFFF 6% (-35°C) for areas with extreme freezing conditions.
Q: What storage conditions preserve the Afff Foam Liquid's effectiveness?
A: Store in sealed containers at 5–40°C, away from direct sunlight and heat. Avoid freezing (use insulated storage for cold regions) and check for color changes or sediment every 6 months-these signal degradation.
Q: What's the correct water - to - Afff Foam Liquid mixing ratio for the AFFF 6% Series?
A: The ratio is 6% concentrate to 94% water. Use clean, non - saline water and mix thoroughly in dedicated tanks or proportioning systems. Verify with a hydrometer to ensure accuracy.
Q: How to test if Afff Foam Liquid meets performance standards before use?
A: Conduct a small - scale test: generate foam using the system, measure expansion ratio (e.g., 7.9±1 for -1°C model) and 25% drainage time. Check film formation on a flammable liquid surface-proper film spread confirms effectiveness.
Q: Are there environmental considerations when using Afff Foam Liquid?
A: Modern AFFF 6% formulations are less harmful, but minimize runoff into water sources. Follow local regulations for disposal-collect used foam and contact hazardous - waste services. Avoid direct release into ecosystems.
