The domestic flame retardant market may be facing adjustment-TMPDA-Tetramethylpropylenediamine

With the rapid development of science and technology, the application fields of polymer materials have gradually expanded in recent years. Due to the flammability of polymer materials, the application and research of flame retardants have received global attention. As material additives that reduce the ignition ability of materials, flame retardants have now become important additives for polymer materials.

Currently, the four largest flame retardant markets in the world are: the United States, Europe, Japan and other Asia-Pacific regions. Among the four markets, the fastest growing usage is in other Asian countries. Data show that from 2006 to 2010, the average annual growth rate of global flame retardant usage was 4.1%, while the average annual growth rate in other Asian countries and regions was 12.5%. It is predicted that from 2008 to 2014, the average annual growth rate of global flame retardant usage can reach 4.9%, and sales can reach 7%. That is, the global flame retardant usage and sales in 2014 can reach 262 billion US dollars and 6.1 billion US dollars respectively. (equivalent to RMB 40 billion).

Due to the transfer of the international downstream industry chain, the domestic flame retardant industry is developing rapidly. At present, the consumption of flame retardants in China is 180,000 to 220,000 tons per year. From 2007 to 2011, the use of flame retardants in China increased by an average annual rate of about 15%. It is understood that flame retardant products currently on the market are mainly divided into two categories: inorganic flame retardants and organic flame retardants. Among them, inorganic flame retardants are composed of antimony trioxide, magnesium hydroxide and other flame retardant systems; organic flame retardants include some flame retardant products represented by bromine, nitrogen and phosphorus compounds. It is worth noting that despite the rapid development of my country’s flame retardant industry, the consumption structure of domestic flame retardant products is not reasonable, which is reflected in the huge market share of brominated flame retardants. However, from 2008 to 2010, as the domestic bromine price soared, the trend of brominated flame retardants being replaced by relatively low-priced halogen-free flame retardants continued to intensify, and the market for brominated flame retardants showed a certain shrinkage. state.

At present, the main treaties and regulations that have a greater impact on flame retardants are the Stockholm Convention, EU ROHS and REACH. Among them, the flame retardants that have been included in the list of persistent organic pollutants by the Stockholm Convention are decabromodiphenyl ether and hexabromocyclododecane. With the improvement of people’s environmental awareness, the development of environmentally friendly flame retardants with low toxicity and low smoke will become the goal of my country’s flame retardant industry. For example, flame-retardant polystyrene foam meets B2 flame-retardant standards at most and has been banned from being used as building exterior wall insulation materials in many developed countries. Therefore, if the country establishes that building insulation materials must meet the B1 flame retardant standard, brominated flame retardants such as EPS, which are widely used in the market, will face withdrawal and will turn to polyurethane foam using phosphorus flame retardants.
