What are flame retardants

Flame retardant, a functional additive that gives flammable polymers flame retardancy, mainly designed for flame retardant 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 retardant mainly includes organic flame retardants and inorganic flame retardants, halogenated flame retardants (organochlorides and organic bromide) and non-halogen. Organic is bromine-based, phosphorus-nitrogen-based, nitrogen-based, red phosphorus and compounds as the representative of some flame retardants, inorganic is 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 the polymer itself contains flame retardant components, which has the advantage of having little impact on the performance of polymer materials and lasting flame retardancy.
