The principle of flame retardant of ATH
1, It has the effect of heat absorption. When the fire occurs can be dehydrated to absorb heat, but also can inhibit the temperature rise of the polymer.
2, has the role of dilution, Al (OH) 3 filling, reduce the concentration of combustible polymers to prevent combustion; 3, has the role of covering.
3, has the role of covering. When Al(OH)3 dehydration, will generate a layer of Al2O3 protective film on the surface of combustible materials, can be isolated from oxygen, in order to prevent the continuation of combustion;.
4, It has the effect of carbonization. Flame retardant will produce a strong dehydrating substance under combustion, which can carbonize the plastic, so that it will not produce combustible volatiles, and then prevent the spread of flame.
In addition, the application of aluminum hydroxide in plastics can also improve the material's UV resistance, arc resistance, dielectric properties and other characteristics, and can also improve the controllability of the shrinkage of the material after molding.
