Hexamethylenediamine is one of the important raw materials for HDI
Hexanediamine is one of the important raw materials for the production of HDI, which is mainly made by hydrogenation of adiponitrile, and the production technology of adiponitrile was previously monopolized by overseas leaders. High technical barriers make adiponitrile manufacturers few, supply elasticity is large, and the limited production capacity of a certain set of equipment will lead to large fluctuations in its price, which will be transmitted to the hexamethylenediamine and HDI links.
HDI series products are used in automotive, furniture, aerospace, shipbuilding, energy conservation and environmental protection industries. There are also many fast-growing emerging fields, such as electrophoretic paints, ultra-wear-resistant floor paints, wind turbine blades and tower protective coatings, photovoltaic backsheet adhesive coatings, etc.
Due to the high cost of raw materials and technical difficulties, the price of aliphatic isocyanates is much higher than that of MDI and TDI.
Wanhua Chemical:
It is the only enterprise in China with 10,000-ton HDI production capacity
The 180,000 tons/year hexamethylenediamine project is a key project for the strategic development of Wanhua's HDI industry chain. The project will ensure the supply of hexamethylenediamine raw materials, rely on the advantages of Wanhua Industrial Park, extend the HDI industrial chain to the upstream, and control the product quality from the source of raw materials while solving the problem of HDI raw material transportation, so that it has unique advantages in the industry.
