Aluminium hydroxide is regarded as being the most important mineral flame retardant in the world and, thanks to its freedom from halogens, it is environmentally friendly and is characterized by its high efficiency as a smoke gas suppressant. This mineral is made from bauxite in accordance with the Bayer process. Besides the flame retardant property, the excellent features of aluminium hydroxide are its high degree of whiteness and low degree of hardness. In addition, dehydration takes place at 200°C.
