Polyether Polyol is an important polyol compound commonly used in the preparation of polyurethane.
Polyether polyols have the following main uses:
1. Polyurethane elastomers: Polyether polyols are the main raw materials for preparing polyurethane elastomers, which can react with polyisocyanates (such as MDI) to form polyurethane elastomers. They are used to manufacture elastic materials such as furniture, car seats, mats, shoe soles, etc.
2. Polyurethane spray coating: Polyether polyols can form two-component polyurethane spray coatings with isocyanates, which are used for coating automobiles, building exterior walls, roofs, pipelines, etc., providing protection and decorative effects.
3. Polyether polyol toughening agent: Polyether polyols can be used as toughening agents for thermoplastic or thermosetting resins to improve the toughness and strength of materials.
4. Polyether polyol flame retardant: polyether polyol can be compounded with flame retardant to prepare fireproof materials, such as flame retardant polyurethane foam.
5. Polyether polyol lubricant: Polyether polyols have good lubricating properties and can be used as lubricants. For example, when preparing lubricating grease, polyether polyols can be added to improve the lubrication effect.
In summary, polyether polyols have a wide range of applications, mainly used in the preparation of polyurethane, spray coatings, toughening agents, flame retardants, and lubricants.
