The four processes involved in the flammability of materials are described and related to the various flame retardance mechanisms that may operate. Following this the four practical approaches used in improving flame retardance of materials are described. Each approach is illustrated with a number of typical examples of flame retardants or synthetic procedures used. This overview of flammabilit...

An overview of commercially used flame retardants is give. The most used flame retardants are illustrated and the seven major markets, which use 96% of all flame-retarded polymers, are described. Annual flame retardant growth rate for each major market is also projected. Toxicity data are reviewed on only those compositions that are considered commercially significant today. This includes 18 co...

Mechanisms for flame retardation are reviewed and general principles developed. Approaches for utilizing flame retardants in various systems are discussed. Structure and flammability relationships are developed. Recent developments in flame retardants are presented. Market forecasts and directions are reviewed.

Restrictions on the use of polybrominated diphenyl ethers (PBDEs) have resulted in the use of alternative flame retardants in consumer products to comply with flammability standards. In contrast to PBDEs, information on the occurrence and fate of these alternative compounds in the environment is limited, particularly in the United States. In this study, a survey of flame retardants in San Franc...

With the phase-out of PentaBDE in 2004, alternative flame retardants are being used in polyurethane foam to meet flammability standards. However, insufficient information is available on the identity of the flame retardants currently in use. Baby products containing polyurethane foam must meet California state furniture flammability standards, which likely affects the use of flame retardants in...

Preface In 2005 Norway nominated the brominated flame retardant commercial pentabromodiphenylether (c-PentaBDE) as a persistant organic pollutant (POP) to be evaluated for inclusion in the Stockholm Convention. Based on its Risk Profile developed in 2006 and its Risk Management Evaluation Report developed in 2007, the POPs Review Committee (POPRC) concluded that global action on c-PentaBDE is w...

Flame Retardants in Discarded Foam Products New furniture labeling and flammability standards in California are expected to offer a market-driven solution for people who want to avoid flame retardants.

An HPLC-UV/MS method has been developed to identify and quantify flame retardants in post-consumer plastics from waste of electric and electronic equipment (WEEE). Atmospheric pressure chemical ionisation spectra of 15 brominated and phosphate-based flame retardants were recorded and interpreted. The method was applied to detect flame retardant additives in polymer extracts obtained from pressu...

this study was conducted to identify emission characteristics of certain hazardous substancescontained in the plastic of used home electrical and electronic appliances keeping in view compliance with therestriction of hazardous substances (rohs) directive and to estimate the possibility of safe recyclingpractices. according to the results, the concentration of cadmium, lead, mercury and chromiu...
