The advantage of additive flame retardants is that they are easier to process, is widely used, and can be added to almost any polymer substrate. , however, the disadvantage of is that it is not compatible with the polymer, is easy to migrate out, and the addition of too much will reduce the mechanical properties of the polymer. In addition, additive flame retardants are mainly added to polymers by mechanical mixing methods, , which means that it has little impact on the performance of polymer materials, , but the flame retardancy persistence is relatively poor 12.
The reactive flame retardant has the advantages of good stability, is not easy to move out, is relatively high durability, is better to maintain the physical and mechanical properties of the polymer. , however, its disadvantage is that the processing is more difficult, not all polymers can be added by reaction flame retardants, and there is no plasticizing effect, is only suitable for thermosetting plastic2.
In summary, the choice of additive flame retardants or reactive flame retardants depends on the specific application needs and processing conditions. If a wide range of application compatibility and a relatively simple processing process are required, additive flame retardants are the better choice. If higher stability and durability are required, and less effect on the properties of the polymer material, may be more suitable for reactive flame retardants.
