HDI (hexamethylene diisocyanate) plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive. This article will detail the upstream and downstream associated products of HDI.

upstream products:

1. hexamethylene diamine: hexamethylene diamine is one of the main raw materials for HDI production, which forms HDI by reacting with phosgene. The production methods of hexamethylene diamine mainly include aniline method, butadiene method and adipic acid method.
2. phosgene: phosgene is another important raw material for the production of HDI, which reacts with hexamethylene diamine to form HDI. As a toxic gas, phosgene needs to be produced and used under strict safety measures.

downstream products:

1. Polyurethane coatings: HDI, as an important isocyanate raw material, can be used to produce polyurethane coatings. Polyurethane coatings have excellent weather resistance, chemical resistance and decoration, and are widely used in construction, automobiles, furniture and other fields.
2. Polyurethane adhesive: HDI can also be used to produce polyurethane adhesive, which has the characteristics of high strength, water resistance and oil resistance, and is widely used in composite materials, packaging, construction and other fields.
3. Polyurethane elastomer: HDI reacts with other polyols to generate polyurethane elastomer, which has good resilience, abrasion resistance, tear resistance and other properties. It can be used to manufacture tires, seals, shock absorbers and other products.
4. Foam: HDI reacts with other raw materials to generate foam, which has the properties of light weight, heat preservation and sound insulation, and is widely used in furniture, construction, refrigeration and other fields.

In short, HDI plays an important role in the field of chemical production raw materials. Its upstream and downstream related products are extensive, involving many fields, such as construction, automobiles, furniture, packaging, composite materials, etc. With the continuous development of science and technology, the application field of HDI will continue to expand.
