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

Upstream Associated Products:

1. Sorbitol: Sorbitol is an important raw material for the production of rigid foam polyether polyols, usually made from glucose by hydrogenation reduction reaction. Sorbitol has a plurality of hydroxyl groups and can undergo a ring-opening polymerization reaction with an epoxide such as ethylene oxide or propylene oxide to produce a polyether polyol.
2. Ethylene oxide: Ethylene oxide is an important organic chemical raw materials, with sorbitol and other compounds containing active hydrogen ring-opening polymerization reaction, the formation of polyether.
3. Propylene oxide: Propylene oxide is also a common epoxide, and can be reacted with sorbitol to obtain polyether polyols with different properties.

downstream related products:

1. polyurethane foam: sorbitol starter rigid foam polyether polyol is an important raw material for the production of polyurethane foam, which reacts with isocyanate to produce polyurethane foam. This kind of foam plastic has excellent thermal insulation, sound insulation, earthquake resistance and other properties, and is widely used in construction, home appliances, automobiles and other fields.
2. coating: sorbitol starter rigid foam polyether polyol can be used as the base resin of the coating to improve the adhesion, weather resistance, water resistance and other properties of the coating.
3. Adhesives: Polyether polyols can be used to produce adhesives, which have good bonding properties and weather resistance, and can be used in wood processing, construction, automobiles and other fields.
4. Elastomer: Using sorbitol starter rigid foam polyether polyol as raw material, polyurethane elastomer can be produced, which has excellent wear resistance, impact resistance and aging resistance, and can be used to manufacture tires, seals and other products.

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 products cover many fields, which is of great significance for promoting the development of the chemical industry.
