二苯基甲烷二异氰酸酯生产技术进展及市场分析

MDI Production Technology Progress and Market Analysis

二苯基甲烷二异氰酸酯(MDI)是全球产量最大、用途最广的异氰酸酯,其主流生产工艺——液相光气法具有较高的技术和资金壁垒,使其供给端呈现寡头垄断的市场格局。截至2017年底,全球MDI总产能为8.73 Mt/a,消费量为6.5 Mt,预计2022年需求量为8.3 Mt。2017年我国MDI产能为3.53 Mt/a,占全球产能的40.4%,表观消费量为1.852 Mt,预计2022年MDI需求量将达2.5 Mt。不断拓展下游应用市场是推动MDI产业可持续发展的重要途径。

MDI(diphenylmethane diisocyanate)is the most productive and widely used isocyanate in the world.Its main production process,liquid phosgene method,has high technical and financial barriers,which makes its supply side present oligopoly pattern.Supply and demand situation and forecast of MDI Market at home and abroad were analyzed.By the end of 2017,global MDI capacity was 8.73 Mt/a,consumption was about 6.5 Mt,and demand is estimated to be about 8.3 Mt in 2022.In 2017,China’s MDI capacity totaled 3.53 Mt/a,accounting for 40.4%of global total.Apparent consumption was 1.852 Mt,and MDI demand is expected to reach 2.5 Mt in 2022.Continuous development of downstream application market is an important way to promote sustainable development of MDI industry.
