1. introduction

slow rebound polyether polyol is an important chemical raw material, widely used in polyurethane foam, elastomer, adhesive and other fields. Because of its unique properties, such as excellent resilience, compression resistance, weather resistance, etc., the slow rebound polyether polyol has an important position in the production of chemical products. In this paper, the properties and uses of slow rebound polyether polyols are discussed in detail.

2. slow rebound properties of polyether polyols

1. structural characteristics of

slow rebound polyether polyols are usually made of low molecular weight polyols, catalysts, foaming agents and other raw materials through polymerization. Its molecular structure contains a large number of ether bonds and hydroxyl groups, which makes it have good hydrophilicity and resilience.

2. physical properties

slow rebound polyether polyols are usually white or light yellow solid particles or powder, with high melting point and viscosity. At the same time, it has good compression resistance and resilience, and can slowly recover after being subjected to pressure.

3. chemical properties

slow rebound polyether polyol hydroxyl can react with isocyanate and other compounds to generate polyurethane and other polymer compounds. In addition, the slow rebound polyether polyol also has good weather resistance, oxidation resistance and thermal stability.

3. Slow Resilience Polyether Polyol Synthesis

Slow Resilience Polyether Polyol Synthesis There are two main methods: one is prepared by ring-opening polymerization of polyol with epoxides such as ethylene oxide and propylene oxide; the other is prepared by cycloaddition reaction of polyol with carbon dioxide. Both of these methods can give slow rebound polyether polyols with excellent properties.

4. slow rebound polyether polyol use

1. polyurethane foam

slow rebound polyether polyol is one of the important raw materials for the preparation of polyurethane foam. Polyurethane foam has excellent thermal insulation performance, seismic performance and environmental protection performance, and is widely used in building insulation, furniture, automobiles and other fields.

2. Elastomer

Slow rebound polyether polyols can be used to prepare elastomers, such as polyurethane elastomers. This elastomer has excellent mechanical properties, wear resistance and aging resistance, and can be used to manufacture tires, seals, etc.

3. Adhesive

Slow springback polyether polyols can also be used to prepare adhesives. Due to its good adhesion and weather resistance, polyurethane adhesives are widely used in construction, automobile, furniture and other fields.

5. conclusion

slow rebound polyether polyol as an important chemical raw material, has a wide range of applications in polyurethane foam, elastomers, adhesives and other fields. Its unique properties, such as excellent resilience, compression resistance, weather resistance, etc., make slow rebound polyether polyols play an important role in the production of chemical products. With the continuous development of science and technology, the application field of slow rebound polyether polyols will continue to expand, bringing more convenience to people's production and life.
