Brominated flame retardant seven facts

Release date:2017-12-18 Author:鑫洋化工 Click:

With the progress of China's economic development and the living standards of the Chinese people, the hidden dangers of fire accidents have become increasingly prominent. Fire safety has become a serious issue in the national economy and social life. The participation of flame retardants in flammable funds to make them into embarrassing information has become a tense way to control the fire from the source. Brominated polystyrene


Reality 1: fire safety inseparable from the flame retardant

Flame retardants can greatly reduce the incidence of fire, slow down the rate of fire and fire intensity. Extend people's escape and response time, increase opportunities for survivors and win more time for firefighting staff's rescue, thus reducing casualties.

The fire regulations and standards of all countries are forced to demarcate the electronic equipment, construction, transportation, and response to plastic parts (9460, 65.00, 0.69%). The components must be satisfied with the requirements of fire-retardant and fire-resistant, that is, the flame retardant must be added.

According to the European Commission, the use of flame retardants has reduced the number of fire-fighting deaths in Europe by 20% in the past 10 years.

The function of flame retardants has been demonstrated. The National Bureau of Commerce of the United States conducted fire tests on five product categories to test the overall functionality of the flame retardant. Results, compared with those who stay in non-flammable data room, stay in flame retardant information room escape time more than 15 times.

The Greenstreet Berman Symposium by the British Authorities in 2009 noted that after the UK released the Fire and Safety Code for Furniture and Furnishings to improve fire safety and security requirements, the number of cases of fire extinction fell by an average of 54 cases between 2002 and 2007, The number of fatal cases of burn was reduced by 780 cases annually, and the number of fire disasters was reduced by 1065 cases annually.


Reality 2: Brominated flame retardants are still widely used in such thriving economies as Taixi

In the European Union, brominated flame retardants currently covered by REACH's list of authorized substances of high concern currently only provide hexabromocyclododecane, and the brominated flame retardants reached by the candidate list are currently only decabromodiphenyl ether.

The EU's RoHS directive limits the use of two brominated flame retardants, polybrominated biphenyls and brominated polystyrenes, in electrical and electronic equipment.

China's RoHS, the "Measures for the Control of Pollution Caused by Electronic Information Products", also defines polybrominated biphenyls and polybrominated diphenyl ethers instead of all brominated flame retardants.

As a result, there is no law on brominated flame retardants have contempt or affirmative support halogen-free. In the more than 70 kinds of brominated flame retardants currently commercially available, there is a complete ban on the use of carvedilol as long as a hexabromocyclododecane, the remaining brominated flame retardants are still widely used.


Reality 3: The vast majority of brominated flame retardants after severe assessment proved to be harmful to the human body and the situation

Brominated flame retardants contain more than 70 varieties. Self-discussion and risk assessment of chemicals are based on a wide range of chemical substances rather than a chemical substance. It is unscientific and irresponsible to abstractly determine that a large class of substances are toxic .

The vast majority of brominated flame retardants do not carry toxic labels. Many brominated flame retardants are even less toxic than salt, such as tetrabromobisphenol A, a brominated flame retardant with the largest consumption.

The EU's risk assessment of TBBPA in 2006 concluded that its release during negligible use is negligible and does not constitute intimidation of human health. At the end of 2013, the Canadian authorities released a risk assessment report on TBBPA. The results showed that TBBPA did not threaten the situation and human health.

In the past two years, the EFSA food chain contaminants group has made a large number of evaluations of brominated flame retardants that can exist in food. Their assertion is that most of the brominated flame retardants evaluated have no health risk and their presence in food is less than cause for concern. Polybrominated biphenyls, polybrominated diphenyl ethers, hexabromocyclododecane and tetrabromobisphenol A are included here.
