The properties and uses
of high-activity polyether polyols in the field of chemical production raw materials
1. Introduction

High-activity polyether polyols are an important chemical raw material and are widely used in the production of polyurethane, polyester, polyamide and other polymer compounds. Due to their unique chemical and physical properties, highly active polyether polyols play an important role in the field of chemical production. In this paper, the properties and uses of highly active polyether polyols are discussed in detail.

2. the properties of highly active polyether polyols

1. Chemical properties

of highly active polyether polyols is a compound containing multiple hydroxyl groups with high reactivity. The hydroxyl group in its molecular structure can react with acid, ester, amine and other compounds to generate corresponding ester, amide, ether and other compounds. In addition, the highly reactive polyether polyol can be polymerized with a compound such as isocyanate to produce a polymer compound such as polyurethane.

2. physical properties

highly active polyether polyols are usually colorless or light yellow transparent liquids with good fluidity and water solubility. Its viscosity increases with the increase of molecular weight and has strong surface activity.

3. high activity polyether polyol use

1. polyurethane production

high activity polyether polyol is one of the important raw materials in the production of polyurethane, and isocyanate and other compounds polymerization reaction, the formation of polyurethane foam, elastomers, coatings and so on. In polyurethane foam, high activity polyether polyol as a foaming agent can make the foam have good elasticity and toughness.

2. Polyester production

high activity polyether polyol can also be used in the production of polyester, and dibasic acid and other compounds polycondensation reaction, polyester resin. Polyester resins have good heat resistance, chemical resistance and mechanical properties, and are widely used in coatings, adhesives, fibers and other fields.

3. Polyamide production

high activity polyether polyol can also be used in the production of polyamide, polycondensation reaction with diamine and other compounds to generate polyamide resin. Polyamide resin has good heat resistance, wear resistance, impact resistance and mechanical properties, widely used in engineering plastics, fibers, rubber and other fields.

4. conclusion

In conclusion, as an important chemical raw material, high activity polyether polyol plays an important role in the production of polyurethane, polyester, polyamide and other polymer compounds. Understanding the properties and uses of highly reactive polyether polyols will help to better use this raw material and improve the quality and efficiency of chemical production.
