Basic introduction to flame retardants

Flame retardants, functional additives that give flammable polymers flame retardancy, mainly for flame retardant design of polymer materials; There are many types of flame retardants, which are divided into additive flame retardants and reactive flame retardants according to the method of use.
Additive flame retardants are added to the polymer by mechanical mixing method to make the polymer flame retardant, and the additive flame retardants mainly include organic flame retardants and inorganic flame retardants, halogenated flame retardants (organic chlorides and organic bromides) and non-halogen. Organic is a number of flame retardants represented by bromine, phosphorus and nitrogen, nitrogen and red phosphorus and compounds, and inorganic are mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon and other flame retardant systems.
Reactive flame retardants participate in the polymerization reaction as a monomer, so that the polymer itself contains flame retardant components, and its advantages are that the performance of the polymer material is less affected and the flame retardancy is long-lasting.
