Production introduction
Available in three formulations-AFFF 3% (-1°C), AFFF 3% (-16°C), and AFFF 3% (-35°C)-the Afff Liquid Foam Concentrate is tailored to perform in varying temperature conditions. All variants maintain a clear pale - yellow liquid appearance, with pH levels optimized for compatibility with firefighting systems and long - term stability.
Core performance traits of the Afff Liquid Foam Concentrate include low surface tension (16.2–18.7 mN/m) and controlled spreading coefficients (3.5–6.4 mN/m), enabling swift foam spread over fuel surfaces. With a viscosity of ≤20 MPas at 20°C, it ensures smooth flow through hoses and nozzles. Expansion ratios (6.6±1 to 8.3±1) and 25% drainage times (2.5–3.2 min) guarantee durable foam blankets that effectively smother flames.
The freezing points of -1°C, -16°C, and -35°C for each model allow deployment in regions with harsh winters, where conventional concentrates might fail. Whether used in refineries, storage terminals, or cold - climate operations, this Afff Liquid Foam Concentrate delivers consistent, reliable fire suppression.

Products Description
FAQ
Q: Can Afff Liquid Foam Concentrate be used with non - standard firefighting nozzles?
A: While compatible with most standard nozzles, check the nozzle's flow rate and pressure specs. Ensure it can handle the concentrate's viscosity to maintain proper foam generation and distribution.
Q: How does the concentrate behave in high - humidity environments?
A: High humidity may slightly affect storage stability over long periods. Store in sealed containers in cool, dry areas and inspect regularly for any signs of moisture - related degradation.
Q: What's the process for diluting Afff Liquid Foam Concentrate correctly?
A: Follow the manufacturer's guidelines for water - to - concentrate ratios (3% for this series). Use clean water and mix thoroughly in dedicated tanks or proportioning systems to ensure uniform solution.
Q: Can the concentrate be used in marine fire - fighting with saltwater?
A: Yes, but test compatibility first. Saltwater may affect foam properties slightly, so adjust proportioning or conduct small - scale tests to ensure optimal performance.
Q: How to dispose of expired Afff Liquid Foam Concentrate safely?
A: Contact local hazardous - waste disposal services. Do not drain into sewers or natural water sources. Follow environmental regulations to minimize ecological impact.
