What is Sucrose based polyether polyol?
Sucrose-based polyether polyol is a polyol prepared by the reaction of sucrose with epoxy compounds such as propylene oxide (or ethylene oxide).Its molecular structure contains multiple hydroxyl (-OH) groups, which provide active sites for subsequent polyurethane reactions.
Sucrose-based polyether polyols are widely used in the manufacture of polyurethane materials because of their unique molecular structure, high viscosity, high activity and high rigidity.
Sucrose based polyether polyol have many features:
1.High functional degree: The molecular structure of sucrose-based polyether polyols contains multiple hydroxyl groups, which gives them a high functional degree, which can significantly increase the crosslinking density in polyurethane synthesis.
2. Good chemical and physical properties: Due to the introduction of sucrose molecules, polyurethane materials made of sucrose-based polyether polyols tend to have higher hardness and chemical resistance.
3. Good thermal stability: The rigid chain structure of sucrose-based polyether polyols enables it to maintain good stability at high temperatures.
4. Environmental protection: Sucrose is a natural and renewable resource, so sucrose-based polyether polyols help reduce dependence on petroleum-based chemicals and are a more environmentally friendly choice.
Sucrose-based polyether polyols are widely used in the polyurethane industry, especially in the production of hard foam materials.Its main uses include：
1. Rigid polyurethane foam
Sucrose-based polyether polyols are very suitable for the manufacture of hard polyurethane foams because of their high functional and rigid properties.This kind of foam is usually used in insulation materials, such as refrigerators, cold storage, pipelines, building walls and other fields.Hard foam materials have excellent thermal insulation properties and high compressive strength, so they are widely used in the construction and refrigeration industries.
2. Polyurethane composite sheet
Sucrose-based polyether polyols can be used as the core material of polyurethane composite panels, which are widely used in building thermal insulation, decoration, heat insulation and sound insulation applications.The composite sheet is lightweight and has good mechanical strength and thermal insulation properties.
3. Perfusion molding material
In some special applications, polyurethane made of sucrose-based polyether polyols can be used for perfusion molding to prepare high-strength and rigid composite materials.These materials are commonly used in protective components of automobiles, ships, and electronic devices.
4. Structural foam
Sucrose-based polyether polyols are also commonly used in the production of structural foams. Structural foams have high density and strength, which are suitable for supporting and strengthening.For example, it is used as a support material in the furniture and mattress industry.
