Polyester is composed of Pure Terephthalic Acid (PTA) or Dimethyl
Natural polyesters and a few artificial ones are all biodegradable, but most synthetic polyesters are not.
Polyester is a polymer that contains ester function groups in its main line. The term "polyester" as a particular material is often referred to as polyethylene terephthalate (PET). The basic chemicals used to make polyester are produced during refining of oil and natural gas, mainly paraxylene terephthalate (DMT) and ethylene glycol (EG) as raw materials through esterification or esterification.
