Medium Expansion Foam

Angus Fire is the world's largest manufacturer of modern natural protein based foams, and we also offer a comprehensive range of synthetic foams.
Not sure which one to buy? Well, the first question to ask yourself is "Will I ever need to fight a polar solvent fire (a polar solvent is a flammable liquid like alcohol which is soluble in water)?

If your answer is yes (or even maybe) then the foam for you is Niagara. Niagara can be used on polar solvents as well as hydrocarbons. It puts fires out really fast thanks to its "film forming" action. Every bubble has a tough protein skeleton that helps prevent fires from re-igniting and burning back. It's the world's first UL Listed high fluidity multi-purpose foam, which means it can be relied on to flow freely and achieve high levels of accuracy in all types of proportioning equipment. Its sister product Alcoseal can be used with Alcoseal VSA to produce "superstable" foam for suppressing hazardous vapours at spills.

If you may be expected to to attend hydrocarbon spill fires, then the foam for you is Petroseal . Petroseal is the same as Alcoseal except that it cannot be used on polar solvents. It's a firm favourite among Airport Fire Services who need to put out aircraft crash spill fires as quickly as possible.

If your main risk is hydrocarbon storage tank fires, then you don't need a film-forming foam. That's because aqueous films cannot form on the hot fuel surfaces found in tank fires. What you need is foam that can really hold its own in the heat of battle, and they don't come any better than FP70 Plus. FP70 plus is a fully approved 3% FluoroProtein foam that is the industry standard for storage tank fire protection.

If you want to buy a synthetic AFFF, take a look at our top-of-the-range Tridol S We also offer an alcohol resistant AFFF called Tridol ATF

If you still haven't found the right foam, then maybe you have a more specialist risk. If you're interested in marine protection or maybe LNG storage tank protection then you'll need Expandol high expansion foam. Maybe you're interested in Class A forestry or structural fire fighting. In that case, you'll need Forexpan S.  The balanced chemical system in Forexpan reduces the surface tension of water to increase the penetrating power into burning A Class materials. It is highly versatile and can be proportioned at various percentages dependent upon the application required.
