Production introduction
Formulated as a 3% concentrate, AR-AFFF 3% Foam Concentrate requires dilution with 97% water to activate, producing a dense foam blanket that smothers flames and blocks oxygen. Its pale yellow, clear liquid consistency ensures easy integration with standard firefighting systems, while a pH range of 7.2–8.0 minimizes corrosion risk to metal equipment. The concentrate maintains stability across temperatures from -15°C to 40°C, with a freezing point of -12°C, allowing reliable use in cold climates with minimal pre-heating.
Key performance traits of AR-AFFF 3% Foam Concentrate include a surface tension of 16.5–17.8 mN/m, enabling rapid spread over alcohol surfaces, and an expansion ratio of 6.8±1, generating foam that adheres to vertical tanks and containers. Its 25% drainage time (5.2–6.7 minutes) ensures prolonged flame suppression, preventing re-ignition even in gusty conditions. Unlike non-resistant foams, AR-AFFF 3% Foam Concentrate retains integrity when in contact with alcohol, avoiding the "breakthrough" that can reignite fires.
AR-AFFF 3% Foam Concentrate finds critical use in pharmaceutical facilities, alcohol distilleries, chemical storage yards, and laboratory settings. It integrates seamlessly with foam generators, monitors, and handheld extinguishers, adapting to both fixed and portable systems. Regular testing-via foam quality checks and pH monitoring-confirms it retains efficacy for up to 10 years when stored in sealed, cool environments.

Products Description
FAQ
Q: Can AR-AFFF 3% Foam Concentrate be diluted beyond the 3% ratio for cost savings?
A: No. Diluting beyond 3% weakens the alcohol-resistant polymers, reducing foam stability. This increases the risk of breakthrough in alcohol fires, making the solution ineffective. Always adhere to the 3% ratio.
Q: How does the concentrate perform on mixed fuel fires (e.g., alcohol + gasoline)?
A: It effectively suppresses mixed fuels. The alcohol-resistant components handle the alcohol fraction, while the AFFF properties target hydrocarbon fuels like gasoline, creating a versatile solution for complex fire scenarios.
Q: What are the packaging options for AR-AFFF 3% Foam Concentrate?
A: It is available in 25L jerrycans, 200L drums, and 1000L IBC totes. Smaller containers suit portable systems, while larger totes are ideal for fixed installations with high-volume demand.
Q: Is special equipment needed to pump AR-AFFF 3% Foam Concentrate?
A: Standard centrifugal pumps work, but avoid gear pumps-they can shear the polymers, reducing foam quality. Use pumps made of stainless steel or reinforced plastic to prevent chemical reactions.
Q: How to verify the concentrate's alcohol resistance before an emergency?
A: Conduct a "breakthrough test": mix the concentrate to 3%, apply foam to a surface of 50% ethanol, and observe for 5 minutes. If the foam remains intact without dissolving, it retains full alcohol resistance.
