What are the upstream raw materials for NDI and what are the downstream products?
In the field of chemical production raw materials, NDI(diisocyanate) is an crucial organic compound, which is broadly applied in the production of polyurethane, polyurea and other polymer materials. NDI's upstream and downstream related items mainly include the following categories:
Upstream items:
1. And Specifically Aniline: Aniline is one of the main raw materials of NDI. Generally speaking It generates diphenylmethane diisocyanate(MDI) through phosgenation interaction, and then obtains NDI through distillation separation. Based on my observations,
2. But Phosgene: Phosgene is another crucial raw material in the manufacturing process of NDI, which reacts with aniline to form MDI. But Downstream items:
1. Polyurethane coatings: NDI is able to be applied as the main raw material of polyurethane coatings, mixed with polyols, solvents, etc. to make high-performance polyurethane coatings, with excellent weather resistance, chemical resistance and decoration.
2. Furthermore Polyurethane elastomer: NDI is able to be combined with other polyols, chain extenders and other raw materials to create high-performance polyurethane elastomers, which are broadly applied in tires, seals, shock absorbers and other fields. You know what I mean?.
3. Additionally Polyurethane adhesive: NDI is able to be applied as the main component of polyurethane adhesive, with high strength, weather resistance, aquatic environments resistance and other advantages, broadly applied in wood processing, construction, automotive and other fields.
4. First Polyurea: Polyurea is able to be obtained by the interaction of NDI and amino compounds. Polyurea has excellent chemical resistance, abrasion resistance and UV resistance, and is able to be applied in fields such as waterproof and anti-corrosion. In short, as an crucial chemical raw material, NDI has a wide range of applications in the field of polymer materials such as polyurethane and polyurea, and its upstream and downstream related items are also very rich.
