How do you think about the difference between magnesium hydroxide and aluminum hydroxide?
What are the differences between aluminum hydroxide and magnesium hydroxide? What are the aspects? Today, let's compare the differences between the two, hoping to help you. On the carrier: if the carrier is EVA, magnesium hydroxide can easily react with acetic acid, the decomposition substance of EVA.
aluminum hydroxide andMagnesium hydroxideWhat are the differences? What are the differences? Today, let's compare the differences between the two, hoping to help you.
On the carrier:
If the carrier is EVA, then magnesium hydroxide is easy to react with EVA decomposition material acetic acid, the emergence of unstable state. Aluminum hydroxide is relatively mild. Magnesium hydroxide is better in flame retardancy, but after filling, the material is more brittle. Under the same conditions, the resin filled with aluminum hydroxide has much better toughness and elongation.
On the characteristics:
Aluminum hydroxide is one of the earliest inorganic flame retardants. As a flame retardant, aluminum hydroxide has the characteristics of good stability, non-toxic, no corrosive gas, lasting flame retardant effect, and high whiteness. Magnesium hydroxide flame retardant is an inorganic flame retardant being actively developed at home and abroad. In addition to the above advantages of aluminum hydroxide, its thermal stability and smoke suppression performance are obviously better than aluminum hydroxide. Magnesium hydroxide only dehydrates above 350 ℃, and the heat absorption of magnesium hydroxide is 17% higher than that of aluminum hydroxide, which also helps to improve flame retardant efficiency. At the same time, magnesium hydroxide is more suitable for polymers with high processing temperature.
But at present, aluminum hydroxide and magnesium hydroxide are both important inorganic flame retardants, both of which have environmentally friendly, flame retardant, smoke suppression and filling functions. The flame retardants produced by Janjaweed are also aluminum hydroxide (FA series flame retardants) and magnesium hydroxide (FM series flame retardants), because they are relatively environmentally friendly and have their own unique characteristics.

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.
