Flame retardant, a functional additive that imparts flame retardancy to flammable polymers, mainly for flame retardant design of polymer materials; there are many types of flame retardants, which are classified into additive flame retardants and reactions according to the method of use. Type flame retardant. 
The added flame retardant is added to the polymer by a mechanical mixing method to make the polymer flame retardant. Currently, the added flame retardant mainly has an organic flame retardant and an inorganic flame retardant, and a halogen flame retardant (organic Chloride and organic bromide) and non-halogen. Organic is a flame retardant represented by bromine, phosphorus and nitrogen, nitrogen and red phosphorus and compounds. The inorganic is mainly flame retardant systems such as antimony trioxide, magnesium hydroxide, aluminum hydroxide and silicon. 
The type-type flame retardant participates in the polymerization reaction as a monomer, so that the polymer itself contains a flame-retardant component, which has the advantages of less influence on the performance of the polymer material and long-lasting flame retardancy.
