Why is magnesium hydroxide flame retardant?

In order to prevent some easily combustible objects from being ignited, some flame retardants are usually added to play a flame retardant role. Magnesium hydroxide is such an ideal flame retardant additive. This is inseparable from its own characteristics. one Magnesium oxide produced after the dehydration of magnesium hydroxide combustion has high strength and good heat resistance. It can play a protective role, timely block fire sources and harmful gases, and generate pollution-free substances when magnesium hydroxide reacts with acid substances. Two The particle size distribution is uniform, and it can be well compatible with the substrate, with little influence on their mechanical properties. three Strong decomposition ability, high flame retardant efficiency and good smoke suppression ability; Low hardness, low friction and no damage to equipment. four The high thermal decomposition temperature of magnesium hydroxide will also increase the processing temperature of plastics and improve the plasticizing efficiency. five The cost is low, and there is no need to spend a lot of money on the magnesium hydroxide flame retardant in actual production. Therefore, these characteristics of magnesium hydroxide can make it an ideal flame retardant.
