Production introduction
Available in three formulations-AFFF 3% (-1°C), AFFF 3% (-16°C), and AFFF 3% (-35°C)-the Afff Foam For Fire Fighting is designed to perform in diverse temperature conditions, from mild winters to extreme cold environments. All variants maintain a clear pale - yellow liquid state, with pH levels optimized for compatibility with firefighting systems and long - term storage stability.
Key performance attributes of the Afff Foam For Fire Fighting include low surface tension (ranging from 16.2 to 18.7 mN/m) and controlled spreading coefficients (3.5–6.4 mN/m). These properties enable the foam to quickly spread across flammable liquid surfaces, forming a thin, persistent film that cuts off the fire's oxygen supply. With a viscosity of ≤20 MPas at 20°C, the foam flows smoothly through firefighting equipment, ensuring consistent deployment. Expansion ratios (6.6±1 to 8.3±1) and 25% drainage times (2.5–3.2 min) guarantee that the foam blanket remains durable and effective, even against intense fires.
The freezing points of -1°C, -16°C, and -35°C for each formulation allow for reliable use in regions with harsh winter climates, where conventional foams might fail due to freezing. Whether applied in industrial facilities, storage terminals, or cold - climate emergency responses, this Afff Foam For Fire Fighting delivers consistent, life - saving fire suppression.

Products Description
FAQ
Q: How does Afff Foam For Fire Fighting interact with different types of flammable liquids?
A: It works effectively on most hydrocarbon fuels like gasoline, diesel, and oil. For specialty fuels, conduct small - scale tests first to ensure the foam forms a proper film and suppresses the fire as expected.
Q: Can the foam be used in automatic fire - suppression systems without manual intervention?
A: Yes, it's compatible with automatic systems. Ensure the system's sensors, pumps, and nozzles are calibrated to dispense the correct foam concentration for optimal fire suppression.
Q: What impact does sunlight exposure have on stored Afff Foam For Fire Fighting?
A: Prolonged sunlight exposure can degrade the foam's chemical properties. Store in opaque, sealed containers in a cool, dark area to maintain effectiveness.
Q: How to verify the quality of Afff Foam For Fire Fighting before use?
A: Check for changes in color, consistency, or odor. Conduct a small - scale foam generation test to verify expansion ratio, drainage time, and film formation as per the product specifications.
Q: Can this foam be used in combination with other fire - fighting agents like dry chemicals?
A: While possible in some cases, mixing agents can disrupt performance. Use them separately and ensure thorough system flushing between different agents to avoid compatibility issues.
