What efforts have flame retardant manufacturers made on environmental issues
In the halogen-free flame retardant, there is an environmentally friendly flame retardant is also very good, can play a better flame retardant effect in the case of halogen-free, but also in the environmental protection to achieve protection, the specific details are what the following for everyone to introduce.

Halogen-free flame retardants are currently mainly organic and inorganic, halogen and non-halogen. Organic is bromine, nitrogen and red phosphorus and compounds as the representative of some halogen-free flame retardants, inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silica and other flame retardant system.
Generally speaking, organic flame retardant has a good affinity in plastics, bromine halogen-free flame retardant in the organic flame retardant system occupies an absolute advantage, although on environmental issues "criticism" multi-end but has been difficult to have other halogen-free flame retardant system to replace.
Among non-halogen halogen-free flame retardants, red phosphorus is a better halogen-free flame retardant, which has the advantages of small addition amount, high flame retardant efficiency, low smoke, low toxicity and wide application. Red phosphorus is mixed with inorganic halogen-free flame retardants such as aluminum hydroxide and expanded graphite to make composite phosphorus/magnesium. Phosphorus/aluminum; Non-halogen halogen-free flame retardants such as phosphorus/graphite can be used to greatly reduce the amount of halogen-free flame retardant, so as to improve the processing performance and physical and mechanical properties of plastic products. However, ordinary red phosphorus is easy to oxidize and absorb moisture in the air, easy to cause dust explosion, difficult transportation, poor solubility with polymer materials and other defects, the scope of application is limited. In order to make up for this deficiency and expand the application range of red phosphorus, we have adopted the advanced foreign microcapsule coating process to make it become microencapsulated red phosphorus. In addition to overcoming the inherent disadvantages of red phosphorus, microencapsulated red phosphorus has high efficiency, low smoke, and does not produce toxic gases during processing. Its dispersion, physical, mechanical properties, thermal stability and flame retardant properties have been improved and improved.

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.
