Building insulation promotes MDI future market

wallpapers News 2020-08-21
MDI TDI are both raw materials for polyurethane production, but the toxicity of MDI is lower than that of TDI, the molding property of polyurethane products made of MDI is relatively good. In 2001, the domestic dem for MDI was 226000 tons, which reached 1.5 million tons in 2012, with an average annual compound growth rate of 18.8%, higher than the GDP growth rate of the same period in China.

building insulation is the largest consumption area of MDI in the world. In 2012, the consumption composition of MDI in the world was 41% for building insulation, 16% for refrigeration, 9% for automobile, 9% for TPU elastomer 25% for others (including pipeline insulation). In contrast, home appliances are the largest consumer area of MDI in China. In 2012, the consumption composition of MDI in China was 30% for household appliances, 15% for slurry, 12% for building insulation, 9% for vehicles 34% for others (including adhesives). The data shows that the dem for MDI in the field of building thermal insulation in China has not been released, there is a large space in the future.

at present, China is the largest construction market in the world, with an existing construction area of more than 50 billion square meters, the annual new construction volume exceeds 2 billion square meters. However, most of the new buildings in China are still high energy consumption buildings, the building energy consumption has reached 27% of the total social energy consumption. In addition, according to the statistics of relevant departments, the thermal conductivity coefficient of external walls windows in China is 3-4 times higher than that of developed countries, the energy consumption per unit building area of external walls is 4-5 times higher than that of developed countries. Therefore, there is a large space for building energy conservation in China. The experience of

in building energy conservation at home abroad shows that building insulation material is an effective technology to prevent the loss of building energy consumption. Polyurethanes made by MDI are widely recognized at home abroad to meet the requirements of safety, environmental protection energy conservation. Among all the thermal insulation materials, EPS XPS are the worst ones. However, the safety performance of Pu thermal insulation materials, especially PU / inorganic composites, whose flame retardancy reaches B1 B2 levels, is obviously better than EPS XPS materials. In the short term, although EPS XPS are cheaper than Pu, Pu insulation materials have more advantages than EPS XPS in terms of comprehensive cost in the whole life cycle.

recently announced that Mitsui Chemical Co., Ltd. plans to close the TDI project with an annual output of 117000 tons in Ludao plant by the end of 2016, close the MDI project with an annual output of 60000 tons in damutan plant. Although Mitsui chemical's closure of MDI TDI plants has a positive impact on Wanhua chemical (600309) other domestic enterprises, due to its small market share, it is expected that the positive degree will be limited.
