SUMMARY REPORT FOR POLYBROMINATED FLAME RETARDANTS

Material Safety Data Sheet

http://www.nordicscreening.org/
Brominated flame retardants (BFRs) are used to reduce the flammability of polymeric materials and have been utilized in commercial materials for several decades. BFRs can be either additive or reactive. Additive flame retardants are incorporated into the polymer prior to, during or more fre-quently after polymerization. They are used especially in thermoplastics. Additive BFRs are monomer molecules that are not chemically bound to the polymer, so that over time they may migrate out of the product into the environment. In contrast, reactive flame retardants are added during the polymerization process and are chemically bound to material in the product. The bound chemicals are not released from products, but residu-al, unreacted flame retardants present in the product can be released. Re-active flame retardants are mainly used in thermosets, especially polyes-ter, epoxy resins and polyurethanes..... (Brominated Flame Retardants (BFR) in the Nordic Environment)

GENERAL DESCRIPTION OF FLAME RETARDANT AGENT

Flame Retardant is a substance that can be chemically inserted into the polymer molecule or be physically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. There are several classes of flame retardants; Halogenated Hydrocarbons (Chlorine and Bromine containing compounds and reactive flame retardants), Inorganic flame retardants ( Boron compounds, Antimony oxides, Aluminium Hydroxide, molybdenum compounds, zinc and magnesium oxides ), Phosphorous containing compounds (Organic phosphate esters, phosphates, halogenated phosphorus compounds and inorganic phosphorus containing salts).
