Magnesium Hydroxide is a kind of eco-friendly inorganic halogen-free flame retardant. It is widely used in the plastic and rubber industry.
When magnesium hydroxide is heated (340-490 degrees), it decomposes and absorbs the heat on the surface of the combustible to be flame-retardant; at the same time, it releases a large amount of water to dilute the oxygen on the surface of the combustible, and the decomposed active magnesium oxide adheres to the surface of the combustible and further prevents the combustion extension.
Magnesium hydroxide not only does not produce any harmful substances during the entire flame retardant process, but its decomposition products can also absorb a large number of harmful gases and smoke generated by the combustion of rubber, plastics, and other polymers while flame retardant. Active magnesium oxide continuously absorbs the incompletely burned molten residue can quickly stop the combustion while eliminating smoke and preventing droplets. It is an emerging environmentally friendly inorganic flame retardant.
