Magnesium hydroxide flame retardant is a new type of filled flame retardant. It releases bound water and absorbs a large amount of latent heat during thermal decomposition to reduce the surface temperature of the composite filled with it in the flame. It has the function of inhibiting polymer decomposition and cooling the flammable gas produced.
Flame Retardant Mechanism of Magnesium Hydroxide Flame Retardant
Magnesium hydroxide decomposes and absorbs heat from the burner surface to flame retardant when heated (340-490 degrees). At the same time, it releases a large amount of water to dilute oxygen on the burner surface. The decomposed active magnesium oxide adheres to the burner surface and further prevents combustion. Magnesium hydroxide not only does not produce any harmful substances in the whole flame retardant process, but also can absorb harmful gases and smoke produced by the combustion of rubber, plastics and other polymers in large quantities. Activated magnesium oxide continuously absorbs incomplete combustion melting residues, so as to eliminate smoke and prevent droplets while quickly stopping combustion, it is a new development. Environmental friendly inorganic flame retardant.
