Introduction to the Fire Retardant SystemFire triangleThe triangle illustrates the three elements a fire needs to ignite: heat, fuel,and oxygen. A fire occurs when those 3 elements are present and combined in the right mixture. A fire can be extinguished by removing any oneof the 3 elements.As a result, different physical processes need to be considered for fireretardant: Cooling: endothermic decomposition reaction of the flame retardantadditive that causes a decrease in the temperature needed tomaintain combustion, thus limiting the emission of combustible gas by the polymer. Dilution: a release of inert gases (CO2, NH3, H2O, etc.) from the thermal decomposition of additivescontributes to the dilution of combustible gases below the ignition threshold. Formation of a protective layer: some flame retardants lead to the formation of a solid protective layerlimiting the transfer of heat and mass between the polymer and the flame.The fire retardants and their mode of actionThere is no single solution for fireproofing materials. Different options can be used alone or in combination(cooling, inhibition of combustion reaction, thermal protection) in order to achieve the target. However, it isimportant to find the best compromise between improved fire resistance and other requirements such asmechanical properties, weather resistance (water, UV), economic feasibility and environmental issues.These fire retardant options are: Halogenated compounds: Brominated derivatives are the most effective. Very often associated withantimony oxides (synergy), halogenated derivatives exhibit a chemical mode of action mainly in the gasphase. Their performance, which is efficient at even relatively low content, is characterized by thegeneration of opaque and toxic fumes during combustion. Metal hydroxides: mainly aluminium trihydrate, which acts as both a flame retardant and a smokesuppressor. The resulting performance is interesting, but to be effective, these compounds must be usedin very large quantities, often greater than 50% in mass, which will result in a significant decrease ofmechanical characteristics and an increase in density and difficulty of wetting. Phosphate and nitrogen compounds: phosphorus derivatives have the ability to form a protective layerwhen the polymer burns, thus limiting the supply of oxygen and energy to the fuel. Ammoniumpolyphosphates have the advantage of combining the action of phosphoric acid with that of nitrogen inthe gas phase. Intumescent systems: intumescence is the ability of a material to develop a carbon shield of such thicknessthat gas and heat transfers are limited. The recipes involve an acidic substance, an inflating agent and acarbon source that leads to the formation of a «char» when the temperature of the polymer rises. It helpsto limit the spread of fire by blocking the passage of smoke, flame and heat while giving the product alower density than common charged systems.3
