Analysis of the Advantages and Disadvantages of Four Different Cable Flame Retardants
The advantages and disadvantages of the four commonly used cable flame retardants are compared. We can learn more about them. Antimony flame retardant advantages: antimony trioxide can not be used as a flame retardant alone, but can be used in combination with appropriate halogen compounds to play a particularly effective flame retardant performance. Antimony flame retardant synergistic organic mechanism. Disadvantages: heavy metals, toxic, and arsenic homologs, crude products generally contain arsenic and other heavy metals, arsenic trioxide is arsenic. Can not be used as green filler and green flame retardant. 2 Aluminum hydroxide flame retardant advantages: low price, good flame retardancy. Disadvantages: poor heat resistance, dehydration starts at 200 ℃
Four Common Cablesflame retardantThe advantages and disadvantages of the comparison, you can do a detailed understanding
One. Antimony flame retardant
Advantages: Antimony trioxide can not be used as a flame retardant alone, but can be used in combination with appropriate halogen compounds to exert particularly effective flame retardant properties. Antimony flame retardant synergistic organic mechanism.
Disadvantages: heavy metals, toxic, and arsenic homologs, crude products generally contain arsenic and other heavy metals, arsenic trioxide is arsenic. Can not be used as green filler and green flame retardant.
2 Aluminum hydroxide flame retardant
Advantages: low price, good flame retardancy.
Disadvantages: poor heat resistance, 200 ℃ that is to start dehydration, 330 ℃ to 350 ℃ that is completely dehydrated, and the curing of the resin in the aluminum hydroxide dehydration temperature range, resulting in the finished product of synthetic resin foaming, uneven surface, dielectric properties decreased, low yield. Applied to high temperature causes silica gel to fog, product whitening and foaming, dielectric performance degradation, etc. EC ≈ 60-100 μS/cm, easy to absorb moisture.
Three. magnesium hydroxide flame retardant
Advantages: the application of magnesium hydroxide flame retardant (430 ℃ decomposition) non-toxic.
Disadvantages: not acid, acetic acid can dissolve magnesium hydroxide, only suitable for low-grade products. Easy to absorb moisture, poor dispersion, poor dielectric.
Four. Boehmite flame retardant with high heat resistance
Advantages: 1% dehydration temperature is above 350 ℃, dehydration reaches peak value at 500 ℃, EC<50 μS/cm, strong dielectric property, which solves the problem of product defect and dielectric property decrease caused by low dehydration temperature of aluminum hydroxide, and has strong acid and alkali resistance.
Disadvantages: flame retardant slightly lower than aluminum hydroxide, to achieve the same flame retardant properties need to add more. But its biggest feature is high heat resistance, both thermal conductivity, acid and alkali resistance, made of high heat resistance functional materials can improve the added value of products.

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.
