Application of Flame Retardants in Polymers

Why should flame retardants be used?

Every day we are surrounded by polymer products that contain flame retardants. Nearly all polymer materials must consider flame retardants in their formulations whether they are required for consumer safety purposes or to protect the integrity of the product. Flame retardants may slow down or even interrupt the combustion process by physical or chemical action in the solid, liquid or gas phase. They interfere during heating, decomposition, ignition, or flame spread with the course of the fire. For example, in the solid phase, the flame retardant forms a carbonaceous layer on the surface of the polymer by dehydration. The carbonized layer not only prevents further pyrolysis of the polymer, but also prevents internal thermal decomposition products from entering the gas phase and participating in the combustion process. In short, the use of flame retardants is critical for polymer products.

Application of flame retardants in polymers

Characteristics of flame retardants

For its wide applications in polymers, flame retardant must fulfill the following characteristics.

  • High fire protection effectiveness.
  • No effect on mechanical strength and esthetics of protected fibers and textiles.
  • No emission of toxic and corrosive substances during their use.
  • No effect on the emission of toxic and corrosive gaseous products of the thermal decomposition and combustion of the matrix.
  • High chemical stability.
  • Ease of application.
  • Resistance to water (washing) and high humidity.


Flame retardants have been used in many consumers and industrial products to decrease the ability of materials to ignite since the 1970s. Flame retardants are often added to the following products.



Adding flame retardants to furniture such as foam, upholstery, mattresses, carpets, curtains, and fabric blinds can provide an extra layer of fire protection and can increase critical escape time in the event of a fire.

Building and construction materials

Flame retardants used in building and construction materials such as wires and cables provide additional fire protection.


From airplanes to cars to trains, flame retardants can play a key role in protecting travelers from the devastation of fire.

Electronics and electrical devices

Most electronics and electrical devices contain 1 to 9 kg of plastic materials, which are easily ignited when in contact with internal and external electrical currents and heat sources. Without flame retardants so much plastic can release as much heat as 0.6 to 6 liters of gasoline. Flame retardants can enable modern electronic equipment to meet fire safety standards and can be vital to the safety of hundreds of these products.
