Aluminum hydroxide can be used either in combination or alone
Aluminum hydroxide is often used as a flame retardant, but everyone should know that there are many products that can be used as flame retardants, but why do users like to choose aluminum hydroxide.

Aluminum hydroxide is a common flame retardant in our lives, safe and non-toxic. Compared with other flame retardants, it has many advantages, such as: the source of aluminum hydroxide is particularly wide, the price is relatively low, the use of a wide range, and its variety is sufficient to meet the requirements of different industries, and mixed with aluminum hydroxide polymer.
When the temperature of the aluminum hydroxide flame retardant rises to a certain temperature, it starts to absorb heat and releases a large amount of crystal water. The heating rate of the polymer is gradually slowed down, thereby slowing down the burning rate.
The combination of aluminum hydroxide is more sensitive to other types of flame retardants, and can be used not only with other flame retardants, but also alone.
In the independent application process of aluminum hydroxide, in order to achieve its single use effect, the fineness must be improved. Same as other powder raw materials. The fineness is closely related to the mechanical properties of the filling compound. The higher the fineness, the greater the ratio of tensile strength to elongation at break, and the physical properties and processing properties of the material after the outer layer treatment will be improved.
Aluminum hydroxide can also be used in combination with other flame retardants. The common multi-component system is a ternary system composed of aluminum hydroxide, antimony trioxide and decabromodiphenyl ethane, each of which has its own advantages. They can also cooperate in battle.
The oil absorption rate is a key factor affecting the viscosity of the slurry. The greater the oil absorption of the filler aluminum hydroxide, the greater the viscosity of the slurry during application. Under the same conditions, the greater the viscosity of the slurry, the greater the hydroxide content and the smaller the amount of aluminum added.

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.
