BOPET is a polymer material widely used in the field of chemical production, and its upstream and downstream related products are numerous. The following will introduce BOPET upstream and downstream related products in detail.

upstream products:

1. phthalic acid (TPA): one of the main raw materials of BOPET is phthalic acid, which is an organic compound obtained through the production process of petrochemical raw materials through multiple steps.
2. Ethylene glycol (EG): Another main raw material of BOPET is ethylene glycol, which is a colorless and odorless liquid and is widely used in chemical production.

these two raw materials through esterification, polycondensation, stretching and other processes, the final production of BOPET film.

downstream products:

1. Packaging material: BOPET, as a high-performance film material, is widely used in packaging in food, medicine, electronic products and other fields. It has excellent high temperature resistance, low temperature resistance, chemical corrosion resistance and other properties, can improve the shelf life and safety of products.
2. Capacitor film: BOPET film has the advantages of high insulation, high heat resistance, high mechanical strength, etc., so it is often used in the manufacture of capacitors. Capacitors are indispensable components in electronic equipment for storing electrical energy and regulating voltage.
3. magnetic tape: BOPET film can also be used to manufacture magnetic tape, because of its excellent magnetic and mechanical properties, can ensure the high quality and long service life of the tape.
4. Photovoltaic backsheet: BOPET film can also be used to manufacture photovoltaic backsheet, which has excellent weather resistance, ultraviolet resistance and insulation performance, and can improve the efficiency and life of photovoltaic modules.

In short, BOPET, as an important polymer material, has a wide range of applications in the field of chemical production. Its upstream and downstream related products are numerous, involving packaging, electronics, photovoltaics and other fields, which are of great significance for promoting economic development and improving the quality of life.
