HDI: Hexamethylene diisocyanate, also known as 1,6-diisocyanate Hexane cyanate is an aliphatic isocyanate. In HDI products, according to different application fields, HDI A> can exist in different forms, basically including four types of monomer, biuret, TMP addition and trimer. Among them, monomers are mainly used in the manufacture of adhesives, and the other three are basically used in the production of coating curing agents.
The global HDI is still in a technology monopoly, its basic synthesis process is similar to MDI, and there are only a few companies in the world Master the technology of industrialization. They are Covestro and BASF from Germany, Kangrui from France, Asahi Kasei, Tosoh and Mitsui Chemicals from Japan, and Wanhua Chemical from China.
From 2014 to 2018, the compound growth rate of global HDI monomer production capacity reached about 13.4%. =link href=”/HDI/” target=_blank>HDI monomer expansion mainly comes from Covestro, Wanhua and Kangrui. In 2016, HDI It was a year of blowout of monomer production capacity, which increased by 100,000 tons compared with 2015, and the growth mainly came from Kangrui and Covestro. From 2017 to 2018, the growth point of HDI monomer production capacity mainly came from Wanhua.
In 2018, the global production capacity of HDI is mainly concentrated in Asia and Europe. more than 50% of capacity. In Asia, HDI monomers are mainly concentrated in China and Japan. In recent years, China’s new production capacity has expanded rapidly. As of the end of December 2018, China The total production capacity of HDI has reached 150,000 tons per year, accounting for about 42% of the total global production capacity. It is currently the world’s largest HDIThe country with the largest monomer production capacity.
