When magnesium hydroxide is heated at 340 ℃ -490 ℃, it will differentiate and absorb the heat on the surface of the incinerator, and then play the role of flame retardant. Together, a lot of water will be released to dilute the oxygen on the surface of the combustor, and the differentiated active magnesium oxide will adhere to the surface of the combustor, further hindering the progress of incineration.

Secondly, magnesium hydroxide will not produce any harmful substances in the whole flame retardant process, and the differentiated products of magnesium hydroxide can also absorb a lot of smoke and harmful gases from the incineration of polymers such as plastics and rubber. Active magnesium oxide can continuously absorb the melting residues that have not been completely incinerated, so as to stop the incineration quickly, eliminate smoke and hinder droplets, It is a new environmental friendly inorganic flame retardant.
