Definition of Magnesium Hydroxide Flame Retardant

Magnesium oxide produced by decomposition is also a good refractory, and it can also help improve the fire resistance of synthetic materials. At the same time, the water vapor it emits can also be used as a smoke suppressant. Magnesium hydroxide is recognized as an excellent flame retardant with three functions of flame retardant, smoke suppression and filling in the rubber and plastic industry. It is widely used in rubber, chemical industry, building materials, plastics and electronics, unsaturated polyester, paint, paint and other polymer materials. Especially, it can replace aluminium hydroxide with flame retardant effect for coating of mine…

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 generated 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…

Properties of Light Magnesium Oxide

Light magnesium oxide is white light loose amorphous powder. It is odorless, odorless and non-toxic. Light weight occupies about three times the volume of heavy magnesium oxide. Exposure to air is very easy to absorb water and carbon dioxide, insoluble in water and alcohol, and can dissolve in dilute acid to form corresponding magnesium salt solution.
