The development trend of flame retardant manufacturer
Edit: Taizhou New Material Co., Ltd.Date: 2016-07-02

  • Just like any other industry, the development trend of flame retardant manufacturers are also diversified, green, high performance technology. Currently most common flame retardants into the market for aluminum hydroxide, magnesium hydroxide as a representative of inorganic flame retardants, brominated, and as the representative of the organic phosphorus flame retardants flame retardants.

  • Data show that 2013 ATH over brominated flame retardants to become the world's largest amount of flame retardant, flame retardant 33% of the total amount. Aluminum hydroxide as a representative of inorganic flame retardant thermal decomposition at high temperatures, absorb a lot of heat to reduce the surface temperature of the polymer; some flame retardants can also decompose water vapor, absorb large amounts of latent heat, reducing the synthesis of materials in flame surface temperature and dilute polymer surface concentration of the flammable gas.

  • This type of inorganic flame retardant and good stability, not evaporation, precipitation, low toxicity and does not cost advantages. But in content, dispersion, polymer processing and mechanical properties of, there is still room to improve. Industry experts believe that inorganic flame retardants will be the future development of Super fine and high affinity, and improve its synergies. Such as the development of smaller particle size of inorganic flame retardant, reducing wear and tear on equipment. Surface modification agent such as through the development of efficient, enhancing the compatibility of inorganic flame retardant and body material, reduce the impact on processing and mechanical properties. Flame retardant effect of aluminum hydroxide, modification can be functional, utilizing the synergistic effect to improve flame retardancy.

  • Bromine, phosphorus, organic flame retardant, high polymer will be the main direction of these products in the future. Han Songqing told reporters that the compounds being absorbed by the body will first on the human body and adversely affect the ecology and polymers of molecular weight greater than 1000 to absorbed by the digestive tract, and thus cannot be through participation in the metabolism of the damage on the human body. EU REACH regulations and United States were given to the toxic substances Control Act of macromolecular aggregates-type flame retardant agent "exemptions", listing it as no registration is required to use the substance.

  • In addition, the intumescent flame retardant and flame-retarding industry focused research areas. It is understood that currently realize industrialization of intumescent flame retardant is not much. This system formed by acid source, carbon source, and the source, in heating or burning process, sources of acid esterification reaction with the carbon source, so that the latter dehydrate form a porous layer of Coke. The carbon layer able to isolate heat transfer, prevents oxygen from entering the combustion area and inhibit the release of flammable products. In air when heated to decomposition processes can release a large amount of toxic and flammable gas compounds can dilute material during combustion gases. It is understood that catalyzed into carbon and its multifunctional composite flame retardant is development of intumescent flame retardant. This technique by adding metal oxides, silicon and boron compounds have synergistic effects of additives such as, improving previous addition of intumescent flame retardant, char unstable defects, increase the amount of charring, improve the quality of carbon layer, ultimately retarding effect increased significantly.

  • In recent years, the flame retardant industry has a revolutionary technique. The Chinese Academy of engineering academician, Professor at Sichuan University syntheses team developed a without adding nitrogen, phosphorus, bromine flame retardant elements such as the char formation flame retardant copolyester. At high temperatures, with a specific structure and does not contain monomers can promote the modification of polyester flame retardant elements, making it a large number of char, so as to achieve a good effect. And because they do not contain flame retardant elements, units in the process of flame retardant cross-linked and non-metal, the complete elimination of the traditional polyester flame retardant systems in the inevitable problem of metal. In addition, the design and synthesis of copolyesters containing only carbon, hydrogen, oxygen, three basic elements, will not have any adverse impact on humans and the environment. The technique in flame-retarding industry of high concern, industry experts have said that this only through the design of structures and changes, rather than adding flame retardant elements, you can achieve the purpose fire retardant technology revolutionized the system guidelines.
