Should know the rational use of flame retardant science

Secretary general of China flame retardant society Zhou Zhengmao says, the selection of flame retardants to juggle many factors, such as compatibility with material, price stability, fire prevention performance, flame retardant, etc. According to its different fire retardants mechanism and compatibility and flame retardant materials, in different applications have their own advantages, to replace not only there is no need to blindly, may increase the risk of new instead. Relative to the application of risk assessment for a longer time data perfect bromine flame retardants, other types of flame retardants of toxicology and the environmental impact study is less, the possibility of unknown risk. University of Amsterdam, according to a recent study shows that replacement of phosphorus-containing flame retardant tend to lack enough ecological toxicity test data.
In the recycling of waste, compared with other flame retardants, bromine flame retardants exhibited superior recyclability and stability. Containing bromine series flame retardant plastic after recycling can keep the same as the original material mechanical properties and fire rating. Japan, the United States and the European studies have shown that contain bromine series flame retardant plastic recycling link after several times can still maintain its mechanical properties and flame retardant properties. The eu also showed that the risk assessment report containing flame retardants can use environmentally friendly way to electrical and electronic equipment for processing, fully able to achieve in WEEE (scrap) to electrical and electronic equipment directive and eu emissions regulations.
