flame retardants are functional additives that impart flame retardancy to flammable polymers. according to the different components, it can be divided into three types: inorganic flame retardants, organic flame retardants and organic and inorganic mixed flame retardants. inorganic flame retardants are currently the most widely used type of flame retardants, mainly hydrates of hydroxides and oxides of aluminum, magnesium, boron, antimony, and molybdenum. the application products include aluminum hydroxide, magnesium hydroxide, monoammonium phosphate, diammonium phosphate, ammonium chloride, boric acid, antimony trioxide, silicon, etc. organic flame retardants mainly include organic halides (organo bromine and organic chlorine), organic phosphide, organic nitrogen, and organic phosphorus/nitrogen intumescent type. among them, halogen-based flame retardants are currently one of the largest organic flame retardants in the world.
chemical flame retardants are widely used in plastic products, textiles, building insulation materials, upholstered furniture and children's products to enhance the fire resistance of products, but most of the flame retardants are toxic, which may lead to lower birth rates and congenital malformations of newborns. , children with mental retardation and hormonal disorders and other health hazards, some flame retardants are also refractory and bioaccumulative, threatening the environment and human health. with the in-depth understanding of the developmental toxicity, endocrine disruption, reproductive toxicity and other hazards of flame retardants, combined with the current use of flame retardants, the european union and many states in the united states have introduced bills to restrict the use of flame retardants in children's products.
