Polymers are used in several industrial applications such as transport, building, electrical and household appliances mainly because they are light in weight, do not corrode, can be tailor-made based on the applications, easy and cheap to produce and easy to recycle. However, they are flammable, causing severe casualties and property damages because they are organic. Flame retardant (FR) additives are therefore used to reduce the flammability of polymer materials. The main safety philosophy behind the use of such FR additives is to prevent ignition and limit fire spread if ignition occurs. This requirement is frequently fulfilled today by using halogen-based FR additives, based on chlorine and bromine compounds. The environmental agencies have increased their concerns and restrictions regarding the use of halogen-based FR additives due to their persistent and Endo chronic effects, making it necessary to replace halogenated FR with other alternatives that are free from halogens.
