Flame retardant additives, also known as flame retardants, are a functional additive that imparts flame retardancy to flammable polymers. According to its application, it can be divided into additive flame retardant and reactive flame retardant. According to the composition, the additive flame retardant mainly includes inorganic flame retardants, halogen flame retardants (organic chlorides and organic bromides), phosphorus flame retardants (erythr phosphorus, phosphates and halogenated phosphates, etc.) and nitrogen. It is a flame retardant.
The reactive flame retardant additive mainly refers to a monomer containing a reactive functional group of an organic halogen and an organic phosphorus. Further, a molybdenum compound, a tin compound, and an iron compound having a smoke suppressing action are also in the category of a flame retardant. It is mainly suitable for materials with flame retardant requirements to delay or prevent the burning of polymer materials. It makes its ignition time increase, ignites itself and is difficult to ignite.
With the widespread attention to safety and health awareness, environmentally-friendly flame retardant additives have been the focus of research and development and application, and have achieved certain results. Flame retardants are classified according to effective elements and can be classified into phosphorus, chlorine, bromine and sulfhydryl, aluminum based, boron based flame retardants and the like.http://www.china-zhufengchem.com/
