Production introduction
The 3% concentrate of Afff Fire Fighting Foam is optimized for high-pressure systems, while the 6% variant works seamlessly in low-flow setups, making it versatile for industrial plants, fuel storage depots, and airport runways. Both formulations exhibit a clear to pale yellow appearance, with a pH range of 7.2–8.6, ensuring compatibility with metal and plastic firefighting equipment. Key performance metrics include a surface tension of 15.5–17.0 mN/m, allowing swift spread across liquid surfaces, and an expansion ratio of 6.8±1, producing a dense foam blanket that adheres to vertical structures.
Afff Fire Fighting Foam excels in extreme temperatures, operating effectively from -15°C to 60°C without compromising stability. Its 25% drainage time of 4.0–5.2 minutes ensures prolonged fire suppression, while its ability to extinguish small hydrocarbon fires in under 30 seconds makes it a critical tool for rapid response. Unlike traditional foams, it resists breakdown when exposed to radiant heat, maintaining its barrier properties even in intense fire conditions.
Storage of Afff Fire Fighting Foam requires sealed, UV-resistant containers to preserve surfactant integrity. Its 10-year shelf life, when stored at 5–40°C, ensures long-term readiness. Whether deployed via handheld extinguishers, fixed systems, or mobile units, Afff Fire Fighting Foam delivers consistent, life-saving performance, making it a cornerstone of modern fire safety protocols.

Products Description
FAQ
Q: How does Afff Fire Fighting Foam interact with water-based extinguishing agents?
A: It is compatible with water-based agents but should be applied first to form a barrier. Mixing during application may dilute the foam's concentration, so apply sequentially for optimal results.
Q: Can Afff Fire Fighting Foam be used in marine environments with saltwater dilution?
A: Yes, but saltwater may slightly reduce expansion ratio. Use a 10% higher concentrate ratio (e.g., 3.3% instead of 3%) to compensate, and flush equipment with freshwater afterward to prevent corrosion.
Q: What measures reduce environmental impact when using Afff Fire Fighting Foam?
A: Choose low-fluorine formulations (compliant with REACH standards) and contain runoff using absorbent booms. Avoid direct discharge into waterways; collect and dispose of used foam via licensed waste management.
Q: How to verify if Afff Fire Fighting Foam is still effective near its expiration date?
A: Conduct a small-scale test: mix the concentrate with water, measure expansion ratio, and check film formation on a hydrocarbon surface. If expansion is below 5.0 or the film breaks within 2 minutes, replace the foam.
Q: Does the foam's performance vary with altitude?
A: At high altitudes (above 2,000 meters), lower atmospheric pressure may increase expansion ratio by 10–15%. Adjust dilution rates slightly (e.g., 2.8% for 3% concentrate) to maintain optimal foam density.
