Magnesium hydroxide is decomposed by heat to produce flame retardant effect
As a new type of filled flame retardant, magnesium hydroxide reduces the surface temperature of the filled synthetic material in the flame by releasing bound water and absorbing a large amount of latent heat when it is decomposed by heat,
As a new type of filled flame retardant, magnesium hydroxide can reduce the surface temperature of the filled synthetic material in the flame by releasing bound water and absorbing a large amount of latent heat when it is decomposed by heat, which can inhibit the decomposition of polymer and cool the combustible gas. Next, let's introduce it to everyone.Magnesium hydroxideFlame retardant mechanism of flame retardant.
When heated, magnesium hydroxide decomposes and absorbs the heat on the surface of the combustion substance to the flame retardant effect. At the same time, a large amount of water is released to dilute the oxygen on the surface of the combustion substance. The active magnesium oxide generated by decomposition adheres to the surface of the combustible substance and further prevents the combustion. Magnesium hydroxide has no harmful substances in its flame retardant process. 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 being flame retardant. Active magnesium oxide continuously absorbs incomplete combustion The melting residue, from the burning to stop quickly while avoiding smoke and preventing melt droplets, is a new environmentally friendly inorganic flame retardant.
Magnesium hydroxide has high decomposition ability, high flame retardant efficiency, strong smoke suppression ability, low hardness, low friction on equipment, and helps to extend equipment life. I hope the relevant introduction of the above content can help you know more about magnesium hydroxide flame retardant.

Zhongke Flame Retardant Organization Watches 20 Closing Ceremonies
On the morning of October 22, 2022, members of Zhongke Flame Retardant New Materials Co., Ltd. watched the closing ceremony of the 20th Congress under the leadership of General Manager Wang Ligui.
Everyone knows that there are two common flame retardants. Today we are going to talk about only one of them. Aluminum hydroxide flame retardant is an environmentally friendly halogen-free flame retardant, which can be widely used in fabrics, wood, plastics, and rubber., Polyurethane and other industries have ideal flame retardant effect. In the process of industrial application, it is found that flame retardant failure occurs when aluminum hydroxide flame retardant is added. The following are the reasons for the failure of aluminum hydroxide flame retardant, how to prevent it, how to deal with the operation, and restore the original function.
As a flame retardant, magnesium hydroxide also need to improve what aspects?
When it comes to flame retardants, everyone is familiar with them. Although we usually have less contact with them, we can know what they are used for from the name. Have to talk about magnesium hydroxide, we all know that its main presentation state is a granular, at present, the market sales of magnesium hydroxide particle size is larger, part of the commodity particle size up to tens of microns, immediately used as a flame retardant, poor dispersion, the physical properties of raw materials greater harm. In industrial production, physical grinding methods are generally used to reduce the particle size to 1 micron. The surface of magnesium hydroxide has high polarity and is easy to agglomerate. As the compatibility of refractory materials and polymer substrates, it not only reduces its flame retardant grade, but also causes more serious harm to the physical properties of raw materials.
