Polyester is a petroleum-based synthetic material typically manufactured as Polyethylene Terephthalate (PET) Resin, and Polyester Staple Fiber (PSF). Polyester has a wide range of end-use applications.
Principal applications include plastic bottles and other containers, apparel and carpets. Polyester is made by combining Terephthalic Acid (PTA) and Monoethylene Glycol (MEG).
Paraxylene (Px), a chemical produced in a crude oil refinery, is the main raw material used to produce PTA. The attached chart depicts the polyester production chain, starting from crude oil, which is converted into Px, which is, in turn, converted into PTA, which together with MEG create various polyester based product offerings.
