What are flame retardants

Flame retardant is also known as flame retardant, fire retardant or fire retardant: it is a functional additive that gives flammability to flammable polymer I; it can be divided into additive flame retardant and reactive flame retardant according to application mode. According to the composition, additive flame retardants mainly include inorganic flame retardants, halogen flame retardants (organic chlorides and organic bromides), phosphorus flame retardants (red phosphorus, phosphate and Halogenated Phosphate), nitrogen flame retardants, etc. Reactive flame retardants are mostly monomers of organic halogen and organic phosphorus containing reactive functional groups. In addition, molybdenum compounds, tin compounds and iron compounds with smoke suppression also belong to the category of flame retardants. It is mainly suitable for plastics with flame retardant demand, delay or prevent the combustion of plastics, especially polymer plastics. It is difficult to ignite because of the increase of ignition time and self extinguishing.
