Do you know the main raw material to use for manufacturing PET resin?

The main raw materials used for manufacturing PET (polyethylene terephthalate) resin are:

1. Purified Terephthalic Acid (PTA): PTA is a key precursor in the production of PET resin. It is derived from the oxidation of p-xylene, which itself is obtained from crude oil or natural gas.
2. Monoethylene Glycol (MEG): MEG is another essential ingredient in PET resin production. It is typically derived from ethylene, which is obtained from either crude oil or natural gas.

These two raw materials, PTA and MEG, undergo a chemical reaction known as polymerization to form PET resin. The process involves combining the PTA and MEG in the presence of a catalyst, heating them to high temperatures, and then rapidly cooling the resulting molten polymer to form solid PET resin pellets. These pellets can then be further processed into various end products such as plastic bottles, containers, fibers, and packaging materials.
