Isocyanate in the sunrise industry
ADI is one of the important raw material for polyurethane materials, the main species include hexamethylene diisocyanate (HDl), isophorone diisocyanate (1PDl), dicyclohexyl methane, 4,4 '- diisocyanate (HuMDl). In addition, ADI also includes four secondary methyl benzene, methyl isocyanate (TMXDl), trimethyl hexamethylene diisocyanate (TM-D1), benzene, 2-methylene diisocyanate (XDl), methyl-ring hexane diisocyanate (HTDl) and other varieties. Which, HDI, IPDI, and H: 2NDI production accounted for 85% of global production for more than ADI.
ADI is currently the world's production of large-scale plants are mainly distributed in Western Europe, North America, Japan and other countries and regions, Germany, Evonik Degussa, BASF and Bayer, Rhodia, France, Japan's Asahi Kasei to master and control the companies ADI of the most advanced manufacturing technology. Which Bayer and Evonik Degussa holds a dominant position, the two companies account for 60% of the world's total production capacity of -70%, followed by Rhodia and BASF.
Currently over 90% of the world's ADI large tonnage, the backbone of products still use the phosgene production, Bayer and Rhodia gasification process using gas-ray production of HDI, IPDI production has accounted for more than half of the world's total output of ADI, However, there is cohabitation phosgene of high toxic and highly corrosive. In recent years, the world's aliphatic isocyanates under the joint efforts of industry, non-phosgene route for synthesis of the research and production has made gratifying achievements in this sunrise industry ADI given even broader prospects for development.
ADI launched the project construction boom
As the ADI huge market potential for development, the world's largest investment companies have launched the construction boom.
Bayer is a leading producer of ADI, using phosgene gas technology to produce HDI and IPDI, liquid phosgene technology to produce Hi2MDI. In 2005, the company is Hj2MDI years ago, the only manufacturer in the United States and Western Europe, built factory HDI and IPDI and its derivatives. July 2002 Bayer Leverkusen in Germany, a base for building a new plant of its HDI production capacity to double to 6 million ton / year in 2007, again a new world-class production base of HDI chose the Shanghai . Evonik Degussa have both isophorone nitrile (IPN), IPDA, and TMDA production plants, IPDI capacity in the United States and Western Europe dominate possession of about 75% of the world IPDI market share, the company is now law and the light of urea were used Theodore gasification plant in France, and He Eren factories IPDI. In 2007 the then invested 10 million euros in Horny to construct a plant, producing isophorone and its derivatives IPDI.
Rhodia is also the United States and Western Europe, engage in the production ADI, which HDI and IPDI adduct in Texas Freeport (Freeport) gasification plant using optical method of production. However, this isocyanate business has been the Swedish specialty chemicals maker Perstorp acquired in July of this year. BASF in Germany, Shi Wazihaide (Schwarzheide) ADI plant using gasification process of urea France and Africa-ray production HDI, IPDI, coating industry due to growing demand for these products, its capacity has been increased to 2 tons / . Japan, Southeast Asia Chemical, Asahi Kasei and Mitsui Takeda ADI also has a production capacity, production plants are located in Kashima, Japan and southeast Asia, the product is mainly HDI, production capacity of about 4 million ton / year.
Concerned about the Chinese market to attract foreign investment
In recent years, China's rapid economic growth, coupled with the 2008 Olympic Games and will be held in Shanghai World Expo 2010 polyurethane material would be a great market demand, thereby stimulating demand for ADI has shown extraordinary growth speed is expected the next few years will continue to grow.
China isocyanate huge market demand, as well as the extraordinary growth rate of the production of high profits, attracts the world's isocyanate production giant of great concern, have invest and build factories in China, and actively participate in market competition, hoping to catch the mystery of China's economic fast development of this bus, and seek in the isocyanate greater development of the industry. Bayer in Shanghai, China an annual output of 50,000 tons Caojing HDI project was started construction in October 2004, by the end of 2006 completed the first phase of the project, the output of 3 million tons / year, according to the market growth of the two is expected to further expand production to 5 million tons / year, and built biuret and trimer production plant. By the end of 2007 Asahi Kasei invest 42 million U.S. dollars of the HDI projects put into operation in Nantong. These large multinational companies setting up factories in China, will promote the development of related industries, will further intensify competition.
On the other hand, Chinese domestic enterprises had not yet been ADI's large-scale production plant. However, It is reported that the industrial zone in Tianjin port, Blue Star has invested 450 million yuan, to be adopting international advanced production technology and experience to build 15 thousand tons / year of the ADI devices. In addition, the polyurethane industry in China Yantai Wanhua leading enterprises are also carried out ADI products and technology reserves.
