Phosphate Flame Retardants (PFRs)

Halogen-containing flame retardants have garnered much attention due to their environmental persistence and possible human toxicity. This has led to the banning and phase out of many of these compounds such as the polybrominated diphenyl ethers (PBDEs).

Consequently, there has been an effort to identify and develop halogen-free alternatives. One such alternative is phosphorus-containing flame retardants (PFRs). This class covers a wide range of both inorganic and organic compounds. Although a small number of these flame retardants do contain chlorine, the majority are halogen free. Included within the organic compound grouping are the phosphate esters.

These compounds are used as flame retardant additives in plasticizers, foams, hydraulic fluids, anti-foam agents and coatings for electronic components/devices. Like the brominated flame retardant compounds, the widespread use of PFRs has raised concerns about their impact on the environment and animal health.

Analysis of indoor air and dust has shown that the concentration of PFRs appears to be higher than that of PBDEs. Additional studies detected PFRs in ground, surface and drinking water. On-going toxicological studies have revealed potential neurological and carcinogenic effects of these compounds, prompting the recognition of ecological and human health concerns.

To aid in the study of these compounds, AccuStandard is providing a number of PFRs for use as reference standards.
