Science USES flame retardants
With the development of our economy and the improvement of people's living standard, fire accidents are becoming more and more obvious. Fire safety has become an important issue in national economy and social life. Adding flame retardant to flammable materials makes it a difficult combustible material, which has become an important means to control fire from the source.
Joint bromine science and environment of China flame retardant society BBS at a news conference in Beijing on September 12, emphasizes the scientific use of flame retardant on the fire prevention of the important role, at the same time, using a large number of scientific facts and data reveals that the safety of bromine series flame retardant, and clarifies some misconceptions on the society.
At present, the amount of new polymer materials and electronic equipment increases significantly, and if it is not treated with strict flame retardant treatment, it will greatly increase the probability of fire occurrence. Therefore, the use of flame retardants is particularly important. At present, there are some misunderstandings about flame retardants in society. First, it is considered that the flame retardant can be dispensable and has little effect. The second is that halogen free flame retardant is green, and the non-halogenation of flame retardant is the future development direction.
There is no doubt that fire safety is inseparable from flame retardants. The efficacy of flame retardants has been proved by many scientific facts. Commercial counsellor's office by the national bureau of standards (five types of products for the fire test, and tested in polystyrene TV shell, computer shell polyphenyl ether, polyurethane foam filling of upholstered seats, with polyethylene rubber cable and wire insulation outsourcing polyester circuit board in the overall efficacy of flame retardants.
The results showed that rooms that used flame retardant materials were 15 times more likely to survive a fire than those without flame retardant materials. The commission's assessment also shows that scientific use of flame retardants has reduced the number of fire deaths in Europe by 20 per cent over the past decade.
Triethyl phosphate (TEP)
Triethyl phosphate(Flame retardants TEP) is mainly used as the high boiling point solvents,catalysts, plasticizers, flame retardants, ethylating agent, and organic peroxide stabilizer. And Triethyl phosphate(TEP) is widely used in medicine, pesticides, vinyl ketone, resins, hydraulic oil and other production areas. In Japan, 70% of this product is used in catalyst.
Cas No:78 -40-0
HS Code HS: 29199000
The most important indicator of product:
colorless transparent liquid,Content ≥ 99.5%, water ≤ 0.20, an acid value of ≤ 0.05, Chroma ≤ 20
Raw materials: phosphorus oxychloride and ethanol-based, two-step synthesis of esterification.
Belong to several categories of dangerous goods:
Currently triethylphosphate TEP general cargo exports are not dangerous.

In fact, bromine flame retardants are still widely used in developed economies such as Europe and the United States. At the regulatory level, the current ban on the banning of bromine flame retardants of the Stockholm convention is only hexabromocyclododecane; Brussels, reach high attention of material authorization list and the candidate list of bromine flame retardants at present only hexabromocyclododecane and ten pbdes, rohs directive only limits the polybrominated biphenyls (PCBS) and polybrominated diphenyl ether two bromine flame retardants in electrical and electronic applications.
China's electronic information product pollution control management method is also limited to the use of polybrominated biphenyls and polybrominated diphenyl ether. In general, there is only one type of hexabromocyclic dodecane currently available in all over 70 commercial brominated flame retardants. The bromine flame retardants have been completely banned, as has been the case in society.
Of bromine series flame retardant human and environmental safety, the eu also gave a scientific risk assessment answer: most of the bromide flame retardants strict assessment, harmless to human body and environment. According to the German fire scientists jurgen troitzsch Dr., the vast majority of bromine flame retardants without toxic label, lot of bromine flame retardants (such as the dosage of the four largest bromine bisphenol a (bpa) of acute toxicity and even below the salt. In 2006, the European Union concluded that the risk assessment of tetrabromobisphenol a was negligible and that it was not a threat to human health. At the end of 2013, the Canadian government published a report on the risk assessment of tetrabromobisphenol a, which also showed that tetrabromobisphenol a was not a threat to the environment and human health.
Pollutants in the European food safety authority food chain group in the past two years to the food of the bromide flame retardants have done a lot of evaluation, the study included polybrominated biphenyls (PCBS), polybrominated diphenyl ether, hexabromocyclododecane and tetrabromobisphenol a, the conclusion is evaluated bromine flame retardants no health concerns, it should not cause concern in food.
Bromine science and environment, said Robert Campbell, BBS President of flame retardants in the normal service condition (such as in electrical and electronic equipment) will release its second evil the story is nonsense, no scientific basis. The transformation of chemical substances is conditional, and no bromine flame retardant can be produced by chemical reaction at room temperature.
