There are many types of flame retardants, and each flame retardant has its advantages and disadvantages, but we should have a development perspective to choose a more suitable and environmentally friendly flame retardant. Because halogen-containing flame retardants have a certain degree of bad influence on the social environment and our lives, they generate more smoke and toxic and corrosive gases (hydrogen halides) when they are burned. This kind of gas is the most dangerous factor in fires. Because their diffusion speed is much faster than that of flames, it hinders people's evacuation and extinguishing work in the fire, causing serious loss of life and property. It is not difficult to see that low-smoke, low-toxic, non-polluting environmentally friendly flame retardants will replace some halogen-containing flame retardants, which also means that the development of environmentally friendly flame retardants is inevitable. Today, Dole Chemical shares some small knowledge about environmentally friendly flame retardants.

With the technological development of environmentally friendly flame retardants and the expansion of application fields, new flame retardants are attracting increasing attention from the public. The main task of current research on environmentally friendly flame retardants is to design and synthesize low-toxicity, low-smoke with multiple flame retardant effects. Innovative environmentally friendly flame retardant, in which blending and copolymerization and embedding of flame retardant components are still the dominant direction of flame retardant polymer materials. Attention must be paid to the research and development of halogen-free flame retardants. With the requirements of polyurethane, polyolefin, and various engineering plastics for flame retardance, research on new varieties of organic phosphorus flame retardants has become increasingly active, and its development trend is to improve thermal stability and flame retardant efficiency, and a series of good performances have appeared. Halogen-free organic phosphorus flame retardant. For environmentally friendly flame retardants, it is both a choice and a trend. It is the responsibility and obligation of everyone to choose a flame retardant that is suitable for them and the environment.
