What are the types of flame retardants

Flame retardant is the application of flame retardant technology in real life. It is a special chemical additive for improving the combustion performance of flammable materials, and is widely used in flame retardant processing of various decoration materials. Materials processed by flame retardant can effectively prevent, delay or terminate the flame propagation when attacked by external fire sources, thus achieving the flame retardant effect. According to different classification standards, flame retardants can be divided into the following categories: 1、 According to the flame retardant elements contained, flame retardants can be divided into halogen flame retardants, phosphorus flame retardants, nitrogen flame retardants, phosphorus-halogen flame retardants, phosphorus-nitrogen flame retardants and so on. 2、 According to different components: inorganic salt flame retardant, organic flame retardant and mixed organic and inorganic flame retardant can be divided according to different components. 3、 According to using methods: according to different using methods, flame retardants can be divided into additive type and reactive type. Additive flame retardants mainly play the role of flame retardants by adding flame retardants to combustibles. 4. Flame retardant suitable for each resin: According to the composition of flame retardant, additive flame retardant mainly includes inorganic flame retardant, halogen flame retardant (organic chloride and organic bromide), phosphorus flame retardant (red phosphorus, phosphate ester and halogenated phosphate ester, etc.) and nitrogen flame retardant, etc.
