Flame retardants are activated by the presence of an ignition source and are intended to prevent or slow the further development of ignition by a variety of different physical and chemical methods.

19 Facts About Flame retardants
2.
Mineral flame retardants are typically additive while organohalogen and organophosphorus compounds can be either reactive or additive.
| FactSnippet No. 1,151,896 |
3.
Mineral flame retardants mainly act as additive flame retardants and do not become chemically attached to the surrounding system.
| FactSnippet No. 1,151,897 |
4.
Non-halogenated inorganic and organic phosphate flame retardants typically act through this mechanism by generating a polymeric layer of charred phosphoric acid.
| FactSnippet No. 1,151,898 |
5.
Flame retardants are typically added to industrial and consumer products to meet flammability standards for furniture, textiles, electronics, and building products like insulation.
| FactSnippet No. 1,151,899 |
6.
However, these questions of eliminating emissions into the environment from flame retardants can be solved by using a new classification of highly efficient flame retardants, which do not contain halogen compounds, and which can be keyed permanently into the chemical structure of the foams used in the furniture and bedding industries.

7.
Mainly brominated flame retardants were found in many environmental compartments and organisms including humans, and some individual substances were found to have toxic properties.
| FactSnippet No. 1,151,901 |
8.
About a dozen halogen free flame retardants were studied representing a large variety of applications, from engineering plastics, printed circuit boards, encapsulants to textile and intumescent coatings.
| FactSnippet No. 1,151,902 |
9.
Tests on the fire behaviour of materials with different flame retardants revealed that halogen free flame retardants produce less smoke and toxic fire emissions, with the exception of the aryl phosphates RDP and BDP in styrenic polymers.
| FactSnippet No. 1,151,903 |
10.
The impact assessment studies reconfirmed that the improper waste and recycling treatment of electronic products with brominated flame retardants can produce dioxins which is not the case with halogen free alternatives.
| FactSnippet No. 1,151,904 |
11.
Furthermore, the United States Environmental Protection Agency has been carrying out a series of projects related to the environmental assessment of alternative flame retardants, the “design for environment” projects on flame retardants for printed wiring boards and alternatives to decabromo diphenylethers and hexabromocyclododecane .

12.
Authors demonstrated for the first time that transplacental transfer of polybrominated flame retardants was associated with the development of children at school age.
| FactSnippet No. 1,151,906 |
13.
Such flame retardants therefore appear to compete for binding sites in the thyroid system, interfering with normal function of thyroid transport proteins in vitro and thyroid hormone receptors.
| FactSnippet No. 1,151,907 |
14.
In some studies, indoor air concentrations of phosphorus flame retardants has been found to be greater than indoor air concentrations of PBDEs.
| FactSnippet No. 1,151,908 |
15.
The U S enacted the Flammable Fabrics Act passed in 1953 after which, flame retardants were mandated to be added to many children's items, including pajamas.
| FactSnippet No. 1,151,909 |
16.
Flame retardants manufactured for use in consumer products have been released into environments around the world.
| FactSnippet No. 1,151,910 |
18.
When products with flame retardants reach the end of their usable life, they are typically recycled, incinerated, or landfilled.
| FactSnippet No. 1,151,912 |
19.
Additive, as opposed to reactive, flame retardants are not chemically bonded to the base material and leach out more easily.
