At present, to a greater influence on the flame retardant the treaty and the regulations are mainly the Stockholm convention and the European Union ROHS and REACH. Which has been the Stockholm convention on persistent organic pollutants (pops) list of flame retardants for ten pbdes and hexabromocyclododecane. Ascension along with the people environmental protection consciousness, the development of low toxicity, low smoke, environmentally friendly flame retardants will be the pursuit of the goal of flame retardant industry in China. For example, flame retardant polystyrene foam up to reach B2 standard, has been banned in many developed countries used for building exterior wall thermal insulation material. So, if once countries establish the building materials heat preservation material to achieve B1 flame retardant standard, the extensive use of bromine flame retardants of EPS on the market will face, such as to use of phosphorus-containing flame retardant polyurethane foam.
