How should flame retardant manufacturers treat halogen-free and halogen-free flame retardants?
Halogen-free flame retardants and halogen flame retardants have different properties, advantages and disadvantages and application fields, and should not be used in favor of one or the other. Different flame retardants should be balanced and coordinated development, play an important role in fire safety.

According to whether it contains halogen elements (mainly bromine and chlorine elements), flame retardants can be divided into halogen flame retardants and halogen-free flame retardants. Among them, the development of halogen-based flame retardants (mainly bromine-based flame retardants) started earlier, the process is mature, and the number has reached nearly 100. Common products include decabromodiphenyl ether, decabromodiphenyl ethane, tetrabromobisphenol A, hexabromocyclododecane, etc.; while halogen-free flame retardants started late, common products include phosphorus-based flame retardants such as phosphate and red phosphorus-based flame retardants, melamine, which are well as melamine, and inorganic mineral flame retardants. At present, the flame retardants used in modified plastics in China are mainly halogen flame retardants, and most of the electronic and electrical products contain halogen flame retardants. Therefore, in the Chinese market, halogen flame retardants have a pivotal position, and showed a sustained and stable growth trend of development.
We believe that this blind promotion of flame retardant halogen-free practice is extremely irresponsible. From a scientific point of view, whether any chemical, including flame retardants, is green is related to its specific chemical structure, and it has nothing to do with whether it contains a certain element. Halogen flame retardants include nearly a hundred products including bromine and chlorine. Although very few products with individual structures do harm to the human body and the environment, most of the products are green and environmentally friendly. Similarly, halogen-free flame retardants are available in many different structures, some of which have been shown to be toxic or highly toxic to the aquatic environment, but most of which are non-toxic and harmless. Therefore, it is an act without scientific basis to deny a large class of products due to the environmental protection problems of individual products.
In addition, based on the risk that any chemicals, including flame retardants, may have not yet been discovered, large flame retardant manufacturers have also actively organized the "Voluntary Action Plan for Release Control (VECAP)", actively calling on manufacturers and downstream users to continuously improve the process, recycle packaging bags, reduce the release of flame retardants to the environment, and minimize potential hazards.
Halogen-free flame retardants and halogen flame retardants have different properties, advantages and disadvantages and application fields, and should not be used in favor of one or the other. Regulatory authorities, industry organizations and industrial chains should pay attention to individual products that have problems or even prohibited by certain regulations, rather than killing a large class of products with one stick, such as all halogen-based flame retardants or halogen-free flame retardants. We should be aware that halogen-free only means that the flame retardant does not contain bromine, chlorine, fluorine, iodine, astatine, the five halogen elements, neither on behalf of green environmental protection, nor on behalf of the development direction of the industry as a whole. Different flame retardants should be balanced and coordinated development, play an important role in fire safety.

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.
