In the past, human beings severely damaged the natural environment and did not realize the importance of environmental protection. Now people's awareness of environmental protection has gradually increased. They pay attention to environmental protection in their daily lives and production activities. Protecting the environment has become our most important thing. In some chemical industries, in order to enable their enterprises to achieve long-term development, they have changed their production methods and continuously developed new environmentally friendly products. Dole Chemical Co., Ltd. in Dongguan is a professional research and development, production and sales New environmentally friendly flame retardant products. The newly developed bellows flame retardant by Daoer Chemical is an environmentally friendly flame retardant without halogen flame retardants.

Many studies have shown that the flame-resistant effect of halogen organic compounds of Shanghai flame retardants decreases in the order of iodine, bromine, chlorine, and fluorine. However, in reality, iodide is unstable and there is a shortage of supplies, which has not been used in practice. Both chlorine and fluorine compounds are not as effective as bromine. The flame retardancy of bromine is generally 2.5-4 times higher than that of chlorine. This is because structurally, the bonding strength of H-Br is greater than that of H-Cl, so the flame retardant effect of bromine compounds is greater than that of similar chlorine compounds. In addition, bromine flame retardants have low toxicity, bromine carbon bonds are weaker than corresponding chlorocarbon bonds, are easily decomposed by heat, and have less residuals in the environment. This factor makes bromide the preferred halogen flame retardant. Bromine-containing inorganic flame retardants are only ammonium bromide, etc. Ammonium bromide has a high flame retardant effect. This is due to the presence of ammonia, which increases the proportion of non-combustible gases in the gas phase, and is currently widely used.
