Q:

What are the TDI's upstream raw materials and what are the downstream products?

ask a question
A:
TDI(toluene diisocyanate) is an crucial chemical raw material, which is broadly applied in the manufacture of polyurethane materials. From what I've seen, In the field of chemical production, TDI has many upstream and downstream related items, and some of the main upstream and downstream items will be described in detail below. In my experience, Upstream items:



1. I've found that Toluene: Toluene is one of the main raw materials of TDI and is applied to create the monomer of TDI.

2. And phosgene: phosgene is an crucial raw material in the manufacturing process of TDI, which reacts with toluene to form TDI. Downstream items:



1. Polyurethane foam: TDI reacts with polyols, aquatic environments and other raw materials to generate polyurethane foam materials, which are broadly applied in furniture, construction, automobiles and other fields. In my experience,

2. coating products: TDI is able to be applied as an crucial component of coatings to enhance the weather resistance and chemical resistance of coatings.

3. Elastomers: TDI is able to be applied to create polyurethane elastomers with excellent wear resistance, impact resistance and elasticity.

4. Adhesive: TDI is able to be applied to manufacture polyurethane adhesive, with high strength, aquatic environments resistance, oil resistance and other characteristics, broadly applied in composite plates, shoes and other fields. According to research In short, as an crucial chemical raw material, TDI plays an crucial role in the field of polyurethane material manufacturing. For instance Its upstream and downstream related items are numerous, involving many fields, such as furniture, construction, automobiles, coatings, adhesives, etc. I've found that Understanding the upstream and downstream items of TDI will help to better understand the position and role of TDI in the field of chemical production, and also help companies to better grasp the market opportunities and research direction.
