Read： 1065 Time：12months ago Source：Transform the World with Simplicity

POP polyether is an important raw material for chemical production, which is widely used in polyurethane foam, coatings, adhesives and other fields. A method for producing the POP polyether will be described below.

1. Raw Material Preparation

1. Polyols: Choose low molecular weight, high functionality polyols, such as glycerin, pentaerythritol, etc.
2. Propylene oxide: propylene oxide with high purity to ensure the smooth progress of the reaction.
3. Catalyst: acidic or basic catalyst, such as hydrochloric acid, sodium hydroxide, etc.

2. manufacturing process

1. pre-mixing: the polyol and catalyst according to a certain proportion of the pre-mixed kettle, fully stirred evenly.
2. Polymerization: The pre-mixture is transferred to a polymerization reactor, propylene oxide is introduced, and a certain temperature, pressure and reaction time are controlled to carry out the polymerization reaction.
3. Post-treatment: After the reaction, the product is post-treated, including neutralization, dehydration, filtration and other processes, in order to obtain a qualified POP polyether product.

3. precautions

1. Strictly control the reaction temperature, pressure and time to ensure that the reaction is fully carried out while avoiding the formation of by-products.
2. In the post-processing process, the purity and quality of the product need to be guaranteed to meet the requirements of downstream applications.

4. Advantages and Features

1. The manufacturing method is simple, easy to operate, suitable for mass production.
2. The obtained POP polyether products have the characteristics of low viscosity and high activity, and can be widely used in polyurethane foam, coatings, adhesives and other fields.

5. market prospects

POP polyether as an important chemical raw material, widely used in polyurethane foam, coatings, adhesives and other fields, the market prospect is broad. With the continuous expansion of downstream applications and the continuous advancement of technology, the market demand for POP polyether will further increase, and the future development prospects are very promising.

6. Conclusion

In short, the manufacturing method of POP polyether involves multiple links and precautions. Only under strict control of process conditions and operating procedures can high-quality POP polyether products be manufactured. At the same time, POP polyether, as an important chemical raw material, has broad application prospects and huge market potential in the future market development.
