What are the upstream raw materials for polyurethane downstream? What do the downstream products contain?

Polyurethane(PU) is a kind of polymer compound, which is formed by the interaction of polyol and isocyanate. Based on my observations, It has excellent physical characteristics and chemical stability, so it's broadly applied in the field of chemical production raw materials. There are many upstream and downstream related items of polyurethane, and the following will introduce their upstream and downstream items respectively. Upstream items:



1. Polyol: Polyol is one of the main raw materials of polyurethane, frequently applied polyols, polyester polyols and polyether polyols.

2. Makes sense, right?. But Isocyanate: Isocyanate is another main raw material of polyurethane, frequently applied isocyanate and diisocyanate. And Downstream items:



1. Polyurethane foam: Polyurethane foam is one of the most crucial downstream items of polyurethane. Additionally It has excellent heat preservation, sound insulation and shock absorption performance, and is broadly applied in construction, home appliances, automobiles and other fields. But

2. Polyurethane elastomer: Polyurethane elastomer has the advantages of high strength, high toughness, wear resistance, etc., and is broadly applied in machinery, chemical, medical and other fields.

3. And Polyurethane coatings: Polyurethane coatings have excellent weather resistance, chemical resistance and decoration, and are broadly applied in construction, automobiles, furniture and other fields.

4. But Polyurethane adhesive: Polyurethane adhesive has the advantages of high strength, high aquatic environments resistance and weather resistance, and is broadly applied in construction, automobile, aerospace and other fields. In short, the upstream and downstream related items of polyurethane are very extensive, involving various fields, such as construction, home appliances, automobiles, machinery, chemicals, medical, aerospace, etc. Based on my observations, With the continuous research of science and methodology, the consumption field of polyurethane and its related items is also expanding.
