Polyether defoamer plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive. This article will detail the upstream and downstream related products of polyether defoamer.

1. upstream associated products

1. ethylene oxide: ethylene oxide is one of the important raw materials for the production of polyether defoamer. It generates polyether by addition reaction, and then further synthesis of polyether defoaming agent.
2. Propylene: Propylene is another important raw material, through the oxidation reaction to generate acrylic acid, and then react with alcohols to generate acrylate, and finally the synthesis of polyether defoamer.
3. Catalyst: In the production process of polyether defoamer, it is necessary to use catalyst to promote the reaction, such as alkaline catalyst.

2. downstream related products

1. Coatings: polyether defoamer is widely used in coating production, which can effectively eliminate the foam in the coating construction process and improve the performance and appearance quality of the coating.
2. Adhesive: In the production process of adhesive, polyether defoamer can prevent the production of foam and improve the uniformity and bonding strength of adhesive.
3. Printing and dyeing auxiliaries: polyether defoamers are often used in printing and dyeing auxiliaries to control foam and improve printing and dyeing effects and product quality.
4. Papermaking chemicals: In the papermaking process, polyether defoamers can be used to control foam, improve the fluidity of pulp and the quality of paper.
5. oilfield additives: the use of polyether defoamer in oilfield additives can effectively eliminate the foam in the process of drilling and oil production, and improve the efficiency of oilfield production. Summary of

:

polyether defoamer has a wide range of upstream and downstream related products, involving many fields. In terms of upstream raw materials, it mainly includes ethylene oxide, propylene and catalysts; in terms of downstream products, polyether defoamers are widely used in coatings, adhesives, printing and dyeing auxiliaries, paper chemicals and oilfield auxiliaries. Understanding the upstream and downstream related products of polyether defoamer will help to better understand its important position and role in the field of chemical production raw materials, and also help enterprises to optimize the production process, improve product quality and reduce costs.
