What is the reason why magnesium hydroxide can be used as a flame retardant?
When magnesium hydroxide is heated (340-490 degrees), it decomposes and absorbs heat on the surface of the combustible material to achieve flame retardant effect; at the same time, it releases a large amount of water to dilute the oxygen on the surface of the combustible object, and the decomposed activated magnesium oxide adheres to the surface of the combustible object and further prevents the Burning proceeds. Magnesium hydroxide not only does not produce any harmful substances during the entire flame retardant process, but its decomposed products can absorb a large amount of harmful gases and fumes generated by the combustion of polymers such as rubber and plastics while being flame retardant. Active magnesium oxide continues to absorb The incompletely burned molten residue can eliminate smoke and prevent molten droplets while quickly stopping the combustion. It is an emerging environmentally friendly inorganic flame retardant.
