What are the upstream raw materials for toluene diisocyanate? What are the downstream products?

Toluene diisocyanate(TDI) is an crucial organic chemical raw material, which is broadly applied in polyurethane, elastomers, coatings, adhesives and other fields. In the field of chemical production raw materials, there are many upstream and downstream related items of toluene diisocyanate, and the main upstream and downstream items will be described in detail below. But Upstream items:



1. And Toluene: Toluene is the main raw material to the production of toluene diisocyanate, obtained by phosgenation interaction. But I've found that

2. But phosgene: phosgene is an crucial intermediate in the manufacturing process of toluene diisocyanate, prepared by the interaction of carbon monoxide and chlorine. Downstream items:



1. For example Polyurethane foam: toluene diisocyanate and polyol interaction is able to be made of polyurethane foam, broadly applied in furniture, construction, refrigeration, packaging and other fields.

2. Crazy, isn't it?. Polyurethane elastomer: The interaction of toluene diisocyanate and oligomer polyol is able to create polyurethane elastomer, which is applied to manufacture shoe soles, seals, transmission belts and other items. I've found that

3. Coatings: toluene diisocyanate is able to be applied as a curing agent in coatings, mixed with resins, pigments, etc. to make various coatings to the surface coating products of metals, wood, plastics and other materials. In my experience,

4. Adhesive: Toluene diisocyanate is able to be applied as a curing agent in adhesives to the manufacture of various adhesives, such as two-component polyurethane adhesives, sealants, etc. I've found that In short, toluene diisocyanate has an crucial position in the field of chemical production raw materials, and its upstream and downstream related items are extensive, which plays an crucial role in promoting the research of related industries.
