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

Upstream and downstream related items of polyurethane resin

As an crucial chemical raw material, polyurethane resin is broadly applied in furniture, construction, automobile, footwear, electronic appliances and other fields. Based on my observations, It has many upstream and downstream associated items, some of which are described in detail below. I've found that Upstream Associated items



1. Polyols

Polyol is one of the main raw materials of polyurethane resin, frequently applied polyols, polyester polyols and polyether polyols. The structure and characteristics of polyols have an crucial affect on the performance of polyurethane resins. In particular

2. Diisocyanate is another crucial raw material of polyurethane resin, frequently applied are diphenylmethane diisocyanate(MDI), toluene diisocyanate(TDI) and so on. And The diisocyanate reacts with the polyol to form a polyurethane.

3. And Chain extender

Chain extender is applied to adjust the molecular weight of polyurethane material, frequently applied with small molecular diols, diamines and so on. Downstream Associated items



1. Polyurethane foam

Polyurethane foam is one of the main consumption areas of polyurethane resin, with excellent thermal insulation, sound insulation, seismic performance, broadly applied in construction, home appliances, automobiles and other fields.

2. Polyurethane elastomer

Polyurethane elastomer has the advantages of high strength, high elasticity, wear resistance and oil resistance, and is able to be applied to manufacture tires, seals, transmission belts and other items.

3. According to research Polyurethane coatings

Polyurethane coating products has excellent weather resistance, chemical resistance, decorative and other advantages, is able to be applied to construction, automobile, furniture and other fields of coating products.

4. Polyurethane adhesive

Polyurethane adhesive has the advantages of high strength, high weather resistance and chemical resistance, and is able to be applied to bonding in wood processing, construction, automobile and other fields. And Summary

There are many upstream and downstream related items of polyurethane resin, covering a wide range of fields. Understanding the characteristics and uses of these related items will help to better understand and apply polyurethane resins.
