Special polyether polyol is an important raw material for chemical production, which is widely used in polyurethane, elastomers, adhesives, coatings and other fields. The upstream and downstream related products of special polyether polyols mainly include the following aspects:

upstream products:

1. Ethylene oxide: Ethylene oxide is one of the main raw materials for the production of polyether polyols. Through the addition reaction of ethylene oxide and polyols, polyether polyols with different molecular weights and functionalities can be produced.
2. Acrylic acid: Acrylic acid and its esters are also important raw materials for the production of special polyether polyols. Through the polymerization of acrylic acid, polyether polyols with special properties can be produced.

downstream products:

1. Polyurethane foam: Special polyether polyol is one of the important raw materials for the production of polyurethane foam. It reacts with isocyanate and other raw materials to produce rigid or flexible foam with excellent performance.
2. Elastomers: Special polyether polyols can also be used to produce polyurethane elastomers. They have the advantages of high strength, high resilience, and wear resistance. They are widely used in tires, seals and other fields.
3. Adhesive: Special polyether polyol can be used as the basic raw material of adhesive, and can react with isocyanate to produce polyurethane adhesive with excellent performance, which is widely used in wood processing, automobile manufacturing and other fields.
4. Coatings: Special polyether polyols can also be used to produce polyurethane coatings. They have excellent weather resistance, chemical resistance, and decoration. They are widely used in construction, automobiles, ships and other fields.

In short, the upstream and downstream related products of special polyether polyols are very extensive, involving many fields, such as polyurethane, elastomers, adhesives, coatings, etc. Products in these fields are widely used in industrial production and daily life, so the production and development of special polyether polyols are of great significance.
