Good foam must be qualified against the effects of thermal radiation negatively, which is also highly flammable substances remaining from its. Include the object's surfaces to be hot in the area by the affected properties due to falling flame spread and cover the fuel. If you do have a good resistance to heat is also assured by General foam mixture is cooling, in a former capital level already exists. 3. resistance of fuel (Fuel Resistance).This means that the fuel in the sanklum hydrocarbons (fuel and flammable substances). The good must have a foam layer the foam film closely to prevent any infiltration of fuel compounds into ingredients to make the foam film, losses and cause burning. 4. the level of fuel vapour (Vapor Suppression).The foam that covers the face seal tightly until I fire requires fuel below cannot be slipped out of touch with the heat, until the flame is ignited, occurred next to them. The foam has outstanding properties, this is largely a group of.Protein foams in reality. There is no any kind of block foam fuel vapor. 100%, because they measure the ability to limit the spread, is not a risk that the fire would get stuck (Reignition). 5. anti-alcohol (Alcohol Resistance).There is a fuel or a combination of alcohol and/or polar solo lawen, which can dissolve in the water as the mixture foams. Make the foam mixture becomes flammable liquids and flames. Therefore,Good foam must be able to prevent or resist such fuel into the water in the mixture.We refer to the foam to resist alcohol and solvent free, ATC, AR-AFFF, AR-FFFP, etc., as well as single family with foam. Keep in mind, no matter what type of foam or is there any properties. When the piercing came out and will need to be able to spread the flame, cover closely and has a durable. If not, it is considered a "low-quality foams fire."
