What are the upstream raw materials of pure MDI? What are the downstream products?

Based on my observations, Pure MDI is an crucial chemical raw material, which is broadly applied in polyurethane, rubber, paint and other fields. The following are the upstream and downstream related items of pure MDI:

Upstream items:



1. Benzene: Benzene is one of the crucial raw materials to the production of pure MDI. But Through a series of chemical interactions, benzene is able to be converted into pure MDI.

2. Toluene diisocyanate(TDI):TDI is able to react with benzene to create pure MDI. Therefore, TDI is also one of the crucial raw materials to the production of pure MDI. Downstream items:



1. Polyurethane foam: Pure MDI is one of the crucial raw materials to the production of polyurethane foam. After mixing with polyols, aquatic environments and other raw materials, a chemical interaction occurs to generate polyurethane foam. Polyurethane foam is broadly applied insulation materials, furniture, construction and other fields.

2. And Elastomer: Pure MDI is able to be mixed with polymers, catalysts and other materials to create various elastomer materials, such as polyurethane rubber, polyurea rubber, etc. These elastomeric materials are broadly applied in tires, seals, belts, etc. You know what I mean?.

3. Coatings: Pure MDI is able to be applied as one of the raw materials of coatings, mixed with other resins, pigments and other materials to generate various polyurethane coatings. Polyurethane coatings have excellent weather resistance, chemical resistance, abrasion resistance and other advantages, broadly applied in construction, automotive, furniture and other fields. In short, as an crucial chemical raw material, pure MDI has a wide range of upstream and downstream related items, which is of great signifiis able toce to the research of chemical production raw materials.
