Polyester

Description

Polyester is a class of polymers that contains ester in its main functional group (which means that at least one hydroxyl group is replaced with an alkoxy group). Polyesters are widely used in the clothing and textile industries, as well as packaging, consumer goods, and more. Polyesters may be thermoplastic or thermoset, often depending on the ester group attached to the polymer chain. See Polyester fiber, Polyester film, or Polyester resin.
