In plastics industry, MEG is an important precursor to a number of thermoplastic resins. It is widely used as a precursor of polyester fibers and resins. Polyethylene terephthalate (PET), which is used to make plastic bottles for carbonated beverages and water, is also used as a precursor. As a drying agent, it is used in the natural gas industry to remove water vapor from natural gas before processing.

Becomes. It can also be recovered with natural gas and reused as an inhibitor.
