Polyester - Wikipedia
WebPolyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. [1] . As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate.
