High threshold, difficult to cross MDI, need to break technical bottleneck

wallpapers News 2020-10-14

industry insiders believe that the authority of MDI project approval is transferred from the State Council to the provincial government, which helps to exp the investment construction of MDI production projects to a certain extent. However, MDI has a high threshold a large amount of investment. It is the key to speed up the construction of MDI projects whether there is a breakthrough in technology.

MDI are the key raw materials of polyurethane industry. It is understood that for a long time, Bayer, BASF, Dow Chemical, Huntsman Mitsui chemical have monopolized the production of MDI for a long time. With the rapid development of China's economy, the dem for polyurethane materials upstream MDI products is increasing. Multinational companies sell MDI products to China through investment export in China, earn high profits. Since the beginning of the 21st century, China Wanhua Chemical Co., Ltd. has made a breakthrough in the annual output of 200000 tons of MDI industrialization project through absorption re innovation. Wanhua chemical strongly joined the MDI camp continuously exped its production capacity through technological innovation. It has deployed MDI projects in Ningbo Yantai, has exped its expansion to overseas. As a result, China's MDI industry has formed a pattern of competition between Wanhua chemical several multinational companies.

according to the statistics of China Polyurethane Industry Association, in 2013, China's MDI production capacity was 1.99 million tons, the output was 1.6 million tons, the operating rate was about 80%. The production capacity of Wanhua chemical reached 1.62 million tons in 2013, ranking first in the world. Bayer is 1.28 million tons BASF is 1.2 million tons, ranking second third respectively in the world. From the perspective of consumption,

, at present, the global MDI consumption is mainly concentrated in Asia, Western Europe North America, the dem accounts for 40%, 35% 20% respectively. Among them, in 2013, China's polyurethane production sales accounted for more than 40% of the world, becoming a global polyurethane production consumption country. Analysts predict that driven by China's sustained economic development, with the change of consumption structure the implementation of energy conservation emission reduction policies, China's MDI dem will increase significantly from about 1.7 million tons in 2013 to 3.55 million tons by 2020, accounting for 40% of the global total. The huge dem for

attracted investors. In order to gain advantages in competition, several major companies have stepped up the pace of MDI capacity expansion in China recently. At present, the 800000 ton MDI integration project of Wanhua chemical Yantai Industrial Park has been started, the original 200000 ton old device has been shut down. BASF Chongqing 400000 tons MDI project was completed in July this year will be put into production in the second quarter of next year. Shanghai Lianheng has also exped MDI production facilities in Shanghai, with an annual capacity of 480000 tons from 240000 tons. The project is expected to be put into operation in 2016. In the next few years, China's MDI capacity will grow rapidly. However, from the current situation, the projects under construction are all dominated by several companies that master MDI production technology.

because of the broad prospect of MDI market, many regions in China regard MDI as the focus of attracting investment. "At present, many regions in northern China, including chemical parks in Hebei Liaoning, will introduce MDI projects as the focus of investment attraction. To a certain extent, the decentralization of project approval authority can promote the investment construction of MDI projects in China Zhu Changchun, Secretary General of China Polyurethane Industry Association, said.

but Zhu Changchun said that there are many factors that need to be considered in order to invest in MDI projects, including market, technology, raw materials, planning, etc., among which technical bottleneck is the most important constraint. "At present, only Wanhua chemical is the only domestic enterprise with mature large-scale MDI production technology. Therefore, unlike many large-scale chemicals, in the field of MDI, enterprises may not be able to think even if they release the government's examination approval." Zhu Changchun said.

at present, there are many enterprises that show the intention of MDI investment in China. As far as foreign enterprises are concerned, there are clear laws regulations on the approval of foreign investment in China. Due to the large scale of investment in MDI production projects, a series of examination approval should be carried out by relevant national departments. In terms of domestic enterprises, in addition to Wanhua chemical, at present, many enterprises are stepping up the research development of MDI production technology, have made certain progress, including Gansu yinguangjuyin, Fangda chemical, Bluestar Group, etc., most of them are TDI, polyether polyol aniline production enterprises.

have been delegated this time, which gives these enterprises local governments more freedom to invest attract investment in MDI projects. However, when investing in MDI production plant, whether the complete set of production technology adopted is mature stable is the core issue.

in addition, there are two factors that need to be considered in MDI investment of Chinese enterprises at this stage. First, from the perspective of existing MDI units, it is basically a continuous or semi continuous production process. Raw material supply, product transportation inventory, downstream dem are all key issues that must be considered in investment. Second, judging from the current industrial layout, the existing MDI devices are mostly located in East China, Jiaodong region Yangtze River Delta region are MDI device intensive areas. BASF Chongqing 400000 ton MDI plant will be put into operation soon, the products will meet the MDI dem of Southwest China. However, there is still a lack of MDI production projects in North China, Northeast China, Northwest China South China. Facing the huge market dem of local surrounding areas, these areas are expected to become the next round of MDI investment hotspots, especially Gansu, Huludao, Cangzhou, Quanzhou, Ordos, Tianjin other regions, which have expressed their intention to attract investment in MDI projects.
