Saturated polyester resin has an important position 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 saturated polyester resin.

upstream associated products:

1. dibasic acid: saturated polyester resin production process requires the use of dibasic acid as one of the raw materials, commonly used dibasic acid including terephthalic acid, isophthalic acid.
2. diol: diol is another important raw material in the production of saturated polyester resin, commonly used diols include ethylene glycol, propylene glycol, etc.
3. Catalyst: In the production process, it is necessary to add a catalyst to promote the esterification reaction. Commonly used catalysts include tetrabutyl titanate, stannous octoate, etc.

the availability, price fluctuations and quality of these upstream raw materials will have an impact on the production of saturated polyester resins.

downstream related products:

1. Powder coating: saturated polyester resin is the main film-forming substance of powder coating, which has excellent chemical resistance, weather resistance and decoration.
2. FRP products: saturated polyester resin can be used as the matrix material of FRP products, and glass fiber reinforced composite made of various FRP products, such as FRP pipes, storage tanks, containers, etc.
3. Adhesive: Saturated polyester resin can be used as the main component of the adhesive for bonding various materials, such as metal, wood, glass, etc.
4. insulation materials: saturated polyester resin has good electrical insulation properties, can be used to make electrical insulation materials, such as insulating paint, insulating sheet, etc.

these downstream product demand changes and technological developments will have an impact on the saturated polyester resin market.

In summary, saturated polyester resins have a wide range of upstream and downstream related products, and their production and application are closely related to the entire field of chemical production raw materials. With the development of science and technology and the continuous expansion of applications, the upstream and downstream products of saturated polyester resin are constantly updated and developed, providing more material choices and solutions for various fields.
