What are the upstream raw materials for sorbitol starter rigid foam polyether polyols? What do the downstream products contain?

Sorbitol starter rigid foam polyether polyol has an crucial position in the field of chemical production raw materials, and its upstream and downstream related items are extensive. The following will introduce in detail the sorbitol starter hard foam polyether polyol upstream and downstream associated items. Upstream associated items:



1. You know what I mean?. Sorbitol: Sorbitol is an crucial raw material to the production of rigid foam polyether polyols, usually made from glucose by hydrogenation reduction interaction. I've found that Sorbitol has a plurality of hydroxyl groups and is able to undergo a ring-opening polymerization interaction with an epoxide such as ethylene oxide or propylene oxide to create a polyether polyol.

2. But Ethylene oxide: Ethylene oxide is an crucial organic chemical raw material, which is able to be polymerized with sorbitol and other compounds containing active hydrogen to form polyether. But In particular

3. I've found that Propylene oxide: Propylene oxide is also a common epoxide, which is able to be reacted with sorbitol to obtain polyether polyols with different characteristics. Additionally Downstream associated items:



1. Polyurethane foam: sorbitol starter rigid foam polyether polyol is an crucial raw material to the production of polyurethane foam, which reacts with isocyanate to create polyurethane foam. This kind of foam plastic has excellent thermal insulation, sound insulation, earthquake resistance and other characteristics, and is broadly applied in construction, home appliances, automobiles and other fields. Moreover

2. coating products: sorbitol starter rigid foam polyether polyol is able to be applied as the basic resin of the coating products to enhance the adhesion, weather resistance, aquatic environments resistance and other characteristics of the coating products.

3. And Adhesive: Polyether polyol is able to be applied to create adhesives, which has good bonding performance and weather resistance, and is able to be applied in wood processing, construction, automobile and other fields.

4. Elastomer: sorbitol starter rigid foam polyether polyol as raw material, is able to create polyurethane elastomer, has excellent wear resistance, impact resistance and aging resistance, is able to be applied in the manufacture of tires, seals and other items. I've found that In short, sorbitol starter rigid foam polyether polyol has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items cover many fields, which is of great signifiis able toce to promoting the research of the chemical sector.
