Flame retardant manufacturers talk about how to do a good job of halogen-free flame retardants?
Halogen-free flame retardant does not contain halogen cable, good flame retardant effect, low smoke and low toxicity of gas generated when decomposed by heat, and is widely welcomed. How to make halogen-free flame retardant materials? Flame retardant manufacturers give you these suggestions:

How to do a good job of halogen-free flame retardant materials?Flame retardant manufacturersGive you these suggestions:
1. Understanding of polymer materials
If you want to be a flame retardant material, you must first have a basic understanding of the degradation mechanism of different polymers, so that you can choose the corresponding flame retardant and polymer coordination, so that the mechanism of the polymer is consistent with the degradation process of the polymer.
2. Understanding Flame Retardants
Everyone often says that halogen flame retardant is relatively better to do a lot, rather than halogen is much more difficult.
In fact, it is well understood that halogen flame retardant relies on free radical termination and antimony halide isolation from oxygen to achieve flame retardant. This flame retardant mechanism is basically universal for any plastic, only the amount of addition. Moreover, halogen flame retardant is much more than the flame retardant that can be selected. Some organic substances are connected with halogen elements, which can basically achieve flame retardant effect. Only processing performance and other properties in the later period need to be considered.
Compared with the universal flame retardant mechanism of halogen, the non-halogen flame retardant mechanism is very limited. For example, phosphorus-nitrogen-based intumescent flame retardant is used in different parts of different plastics. In addition, its mechanism depends on the mechanism of esterification expansion into carbon. Therefore, the addition of many fillers and additives affects its flame retardant mechanism. Of course, flame retardant cannot play the corresponding mechanism.
3. Learning processing technology
Different people with the same formula sometimes have very different performance, which is mainly caused by the processing conditions and screw combination, especially when producing engineering plastics and glass fiber products.
Polymer and flame retardant blend, theoretically, of course, the higher the temperature, the stronger the shear, the better the mixing effect, the better the relative performance, but these are to meet the plastic processing temperature and flame retardant decomposition temperature as the premise of the conditions. When encountering different flame retardants, according to the decomposition temperature of the flame retardant, selecting the appropriate screw combination and processing temperature will get products with good performance (even if there are problems in the first few attempts, you can try to continue to adjust to see if there is any possibility of improvement).
4. Understanding the Additives
Through the addition of additives, the product can make a good surface and performance, of course, additives are not omnipotent, the right place with the right additives is the most important. To make good use of additives, we must first fully understand the structure, principle and use of additives, so as to use it efficiently.
5. Recognize and learn relevant testing methods and standards
There are many standards for flame retardant testing,Different flame retardant system for different flame retardant test may get different results, if we can understand the principle of good flame retardant mechanism and different test standards, for the test standard will be more clear, know what kind of system for different test standards will show how the index and flame retardant performance.

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.
