介绍 | FordaGard FordaGard is the range of fine Aluminium trihydrate (ATH) products manufactured by LKAB Minerals in Europe. FordaGard origins Aluminium trihydrate, also known as aluminium trihydroxide, ATH, or alumina trihydrate, is derived from bauxite ore. This natural ore is refined to a fine white powder via the Bayer process. After washing and drying it is used as the feedstock for a wide range of alumina chemicals. The raw material used for the FordaGard products is from a high purity source. FordaGard product uses
Flame retardant action FordaGard decomposes when exposed to heat yielding aluminium oxide and water by the following reaction: 2Al(OH)3 - Al2O3 + 3H2O The decomposition starts at 180oC and is endothermic with a heat change of -1050J/g, a total loss of 34.7% of the original weight is seen. When incorporated into organic materials such as plastics, textiles and wood, the takes heat away from the flame front. Water vapour near the surface of the burning material leads to oxygen depletion reducing the burning rate of the gases. Smoke suppression action One reason for using FordaGard in flame retardant formulations is its action as a smoke suppressant. The high surface area aluminium oxide formed as a result of decomposition absorbs the combustion products responsible for the formation of soot particles. FordaGard standard grades
