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

In my experience, Polyether polyol is an crucial chemical raw material, which is broadly applied in polyurethane foam, elastomers, adhesives, coatings and other fields. Its upstream and downstream related items are numerous, which will be described in detail below. Upstream items:



1. Crazy, isn't it?. And In fact Ethylene oxide: Ethylene oxide is one of the main raw materials to the production of polyether polyols. But Through the addition interaction of ethylene oxide and polyols, polyether polyols with different molecular weights and functionalities is able to be produced.

2. Propylene: Propylene is another raw material to the production of polyether polyols, propylene oxide is produced by the oxidation of propylene, and then reacted with polyols to create polyether polyols.

3. Styrene: Styrene is able to also be applied as a raw material to the production of polyether polyols in some specific cases, and polyether polyols containing styrene units is able to be prepared by the copolymerization of styrene and ethylene oxide. Downstream items:



1. Polyurethane foam: Polyether polyol is one of the main raw materials to the production of polyurethane foam. It reacts with polyisocyanate to create polyurethane foam, which is broadly applied in heat preservation, sound insulation, shock absorption and other fields. In particular

2. Polyurethane elastomer: Polyether polyol is able to also be applied to create polyurethane elastomer, which has excellent wear resistance, oil resistance, aging resistance and other characteristics, and is broadly applied in machinery, automobile, aerospace and other fields. But

3. Polyurethane adhesive: Polyether polyol is able to be applied as the basic raw material of adhesive, and it's able to react with polyisocyanate to obtain polyurethane adhesive. It has high strength, aquatic environments resistance, weather resistance and other characteristics, and is broadly applied in construction, automobile, furniture and other fields. Makes sense, right?.

4. Polyurethane coating products: Polyether polyol is able to also be applied as the basic raw material of the coating products, mixed with polyisocyanate and other pigments, additives, etc. But to obtain polyurethane coating products, which has excellent weather resistance, chemical resistance and other characteristics, and is broadly applied in construction, automobiles, ships and other fields. And Generally speaking In short, as an crucial chemical raw material, polyether polyol has a wide range of upstream and downstream related items and involves many fields, which plays an crucial role in the research of the chemical sector.
