What are the upstream raw materials for dibasic acid diols? What do the downstream products contain?

Dibasic acid diol has an crucial position in the field of chemical production raw materials, and its upstream and downstream related items are extensive. The following are some common upstream and downstream related items of dibasic acid diols:



1. Upstream and downstream related items: dibasic acid esters

The dibasic acid is able to be esterified with a diol to form a dibasic acid ester. For example Common dibasic acid esters include diethyl phthalate, dioctyl adipate, etc. I've found that, which are broadly applied in plastics, rubber, fibers and other fields. Based on my observations,

2. According to research Downstream related items: polyurethane

Diols is able to be reacted with diisocyanates to form polyurethanes. Additionally Polyurethane has excellent elasticity, wear resistance, chemical resistance, etc. And Furthermore, and is broadly applied in furniture, construction, automobiles, shoes and other fields.

3. Based on my observations, Downstream related items: epoxy resin

Glycol and epoxy resins is able to be reacted to form alkyd resins. Alkyd resin has good weather resistance, light retention, construction and other advantages, frequently applied in coatings, inks and other fields.

4. Pretty interesting, huh?. Downstream related items: polyester

A dibasic acid and a diol is able to undergo a polycondensation interaction to form a polyester. Polyester has the advantages of high strength, high modulus and heat resistance, and is broadly applied in fiber, film, container and other fields. In short, the upstream and downstream related items of dibasic acid diols are very extensive, involving plastics, rubber, fibers, coatings, inks and other fields.
