Flame retardant is a kind of functional assistant which gives flame retardancy to flammable polymer, mainly designed for flame retardancy of polymer materials; there are many types of flame retardants, which can be divided into additive type flame retardant and reactive type flame retardant according to the use method.
At present, the additive flame retardants mainly include organic flame retardant and inorganic flame retardant, halogen flame retardant (organic chloride and organic bromide) and non halogen. Yaji is a kind of flame retardant represented by bromine system, phosphorus nitrogen system, nitrogen system, red phosphorus and compounds. The inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon system and other internal combustion resistance systems.
Reactive flame retardant is a monomer to participate in the polymerization reaction, so the polymer itself contains flame retardant components. Its advantage is that it has little impact on the capacity and use performance of polymer materials, and the flame retardant is durable.
