At present, flame retardant materials are mainly organic and inorganic, halogen and non halogen. High flame retardant materials are bromine, nitrogen, red phosphorus and compounds as the representative of some flame retardants, inorganic mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon flame retardant system.
Generally speaking, organic flame retardants have a good affinity. When used in plastics, brominated flame retardants have an absolute advantage in the organic flame retardant system. Although there are many "criticisms" on environmental protection, it is difficult to replace other flame retardant systems.
