So no need to buy and store 2 types of foams.5Film FormationThe film-forming capacity diminishes beyond a fuel temperature of 90\u00b0C.Polymeric film is not significantly affected by a rise in temperature.AR-AFFF is best suited for hot &amp; deep fire,s as tank fires.6DrainageThe film formed by AFFF Foam gets drained in a short time.It remains stable on the fuel for a longer time and has slow drainage.Slow drainage of AR-AFFF enables the foam to have a better cooling effect.7Burn-back Resistance Test of ISIAs per IS:4989:2006, the minimum burnback resistance time is 8 min.As per IS:4989:Part IV, the minimum burn-back resistance time is 10 min.AR-AFFF foam bubbles are robust and stronger to withstand high temperatures, so the burn back resistance of AR-AFFF is higher.8Sealability Test of ULAfter the fire is extinguished, a sealability test is carried out for 9 min.After the fire is extinguished, a sealability test is carried out for 15 min.AR-AFFF exhibits better burn-back resistance.9Self-healing propertySelf-healing characteristic is shown only at low fuel temperature over non-polar solvents. The film simply dissolves in polar solvents.Self-healing characteristic is shown even at high fuel temperature on both non-polar as well as polar solvents.Better self-healing characteristics of AR-AFFF enable the film to reappear even after it gets disturbed.<\/p>\n<p>Why Choose Kanex Foam Type Extinguishers?<\/p>\n<p>Certified to ISI &amp; UL standards for reliability.<\/p>\n<p>Designed for fast knockdown, better coverage, and strong re-ignition resistance.<\/p>\n<p>Available in multiple sizes and capacities to suit diverse industrial and commercial needs.<\/p>\n<p>Need Expert Advice?<\/p>\n<p>Still unsure which fire extinguisher suits your site best?
