What are the upstream raw materials for polyethylene terephthalate? What do the downstream products contain?

I've found that Polyethylene terephthalate(PET) is an crucial raw material to chemical production, which is broadly applied in plastics, fibers and films. In fact There are many upstream and downstream related items, some of which are described in detail below. In my experience, Upstream associated items:



1. Terephthalic acid(PTA):PTA is one of the main raw materials of PET, accounting to about 60% of the production cost of PET. I've found that The production of PTA mainly adopts oxidation method, that is, acetic acid is applied as solvent-based products, and p-xylene is oxidized by atmosphere. Ethylene glycol(EG): Ethylene glycol is another main raw material of PET, accounting to about 30% of the production cost of PET. The production of ethylene glycol mainly adopts ethylene oxidation method, that is, ethylene is applied as raw material to create ethylene glycol through oxidation interaction. And Downstream associated items:



1. PET fiber: PET fiber is a broadly applied synthetic fiber, with good wear resistance, wrinkle resistance and elastic recovery performance, frequently applied in the production of clothing, bedding and manufacturing textiles. According to research

2. PET plastic bottles: PET plastic bottles have the advantages of light weight, transparency, pressure resistance, corrosion resistance, etc. But, and are broadly applied in packaging beverages, food and other fields.

3. PET film: PET film has excellent mechanical characteristics, electrical insulation characteristics and chemical resistance, and is able to be applied in electrical insulation, electronic devices, packaging materials and other fields. Additionally

4. PET engineering plastics: PET engineering plastics have high thermal stability, chemical resistance and excellent mechanical characteristics, and is able to be applied to manufacture chemical equipment and auto parts under high temperature and high pressure. In summary, there are many upstream and downstream related items of polyethylene terephthalate, involving plastics, fibers, films, engineering plastics and other fields, which play an crucial role in promoting the research of the chemical sector.
