Superfining of aluminium hydroxide

The particle size of aluminum hydroxide directly affects its flame retardant and filling properties. As the particle size becomes finer, the surface area of ATH particles keeps increasing, which is beneficial to its flame retardant performance, and the finer the particle size of the powder, the higher the limiting oxygen index of the material. This is because the flame retardant effect is governed by the chemical reaction, so the smaller the particle size of equal amount of flame retardant, the larger the specific surface area, the better the flame retardant effect. The physical and chemical property test results of inorganic powder materials filled with polymer materials show that ultra-fine inorganic rigid particles can play a toughening and strengthening effect on polymer materials, so ultra-fine aluminum hydroxide particles not only make the system flame retardant performance, but also solve the problem of its impact on mechanical properties.
