US: Following earlier action by the EU, the US Environmental Protection Agency (EPA) is planning to publish guidelines on safer alternatives to the flame retardants that are currently used in consumer and commercial products, including building insulation and products with flexible polyurethane foam.
Flame retardant chemicals such as hexabromocyclododecane (HBCD) and pentabromodiphenyl ether (pentaBDE) raise concerns for human health and the environment, including potential reproductive, developmental and neurological effects that can be persistent, bioaccumulative and toxic to aquatic organisms.
The EPA has identified butadiene styrene brominated copolymer as a safer alternative to HBCD used in polystyrene building insulation. The substitute is currently in commercial production in the US. Additionally, oligomeric phosphonate polyol has been proposed as a safer alternative to pentaBDE.
The European Chemicals Agency (ECHA) is due to decide on 9 July 2014 whether exemptions can be granted to manufacturers of expanded polystyrene (EPS) to continue using HBCD as a flame retardant beyond the August 2015 phase-out deadline. Most international players are switching to the new non-halogen flame polymeric retardant PolyFR.
