Non-Halogen Fire Retardant Magnesium Hydroxide

Magnesium Hydroxide is an inorganic flame-retardant filler of polymer matrix composites with promising applications. Like aluminum hydroxide, magnesium hydroxide flame retardant is flame retardant by relying on the chemical decomposition of heat when it is heated and releases water. Therefore, it is non-toxic, low-smoke, and the magnesium oxide produced after decomposition is chemically stable. Produce secondary pollution and other advantages.Magnesium Hydroxide decomposes when absorbing heat (340-490 degrees) and absorbs the heat from the surface of the combustion material to the flame-retardant effect; at the same time, it releases a large amount of water to dilute the oxygen on the surface of the fuel, and the active magnesium oxide produced by the decomposition adheres to the surface of the combustible and further prevents The burning proceeded. Magnesium hydroxide not only does not produce any harmful substances in the entire flame retardant process, but its decomposed products can absorb a large amount of harmful gases and fumes generated from the combustion of polymers such as rubber and plastic while being flame-retarded, and active magnesium oxide is continuously absorbed. The incomplete combustion of the molten residue, which eliminates smoke and prevents droplets while allowing combustion to stop quickly, is an emerging environmentally friendly inorganic flame retardant.Mg(OH)2(%)≥98.00CaO(%)≤0.05Insoluble(%)≤0.05size(um)D50≤7water(%)≤1.0Fe3+(%)≤0.003
