Allyl alcohol polyether polyol (AEP) is an important raw material for chemical production, which is widely used in polyurethane, coatings, adhesives, elastomers and other fields. Its upstream and downstream related products are numerous, and some of the main upstream and downstream products will be described in detail below.

upstream products:

1. Allyl alcohol: Allyl alcohol is one of the main raw materials of allyl alcohol polyether polyols, used to produce low molecular weight polyether polyols.
2. Ethylene Oxide: Ethylene oxide reacts with allyl alcohol to produce allyl ethyl ether, which is further polymerized to produce allyl alcohol polyether polyol.
3. Catalyst: A catalyst, such as an acidic catalyst or a basic catalyst, is used in the production of the allyl alcohol polyether polyol to promote the polymerization reaction.

downstream products:

1. polyurethane foam: allyl alcohol polyether polyol can be used as a foaming agent of polyurethane foam, reacting with isocyanate to generate rigid foam or flexible foam, which is widely used in heat preservation, sound insulation, packaging and other fields.
2. coating: allyl alcohol polyether polyol can be used as film-forming material of coating, providing good adhesion, weather resistance, chemical resistance, etc., for construction, automobile, ship and other fields.
3. Adhesive: Allyl alcohol polyether polyol can be used to prepare adhesives, such as polyurethane adhesives, acrylate adhesives, etc., for wood processing, building materials, packaging and other industries.
4. Elastomer: Allyl alcohol polyether polyol can be used to prepare elastomers, such as polyurethane elastomers, acrylate elastomers, etc., with excellent wear resistance, impact resistance, oil resistance and other properties, for shoes, automotive parts, seals and other fields.

In short, as an important chemical raw material, allyl alcohol polyether polyol has a wide range of upstream and downstream related products, involving many fields, such as polyurethane, coatings, adhesives, elastomers, etc.
