Polyethylene terephthalate (PET)

Polyethylene terephthalate is derived from xylene and is one of the most widely used industrial polyesters. It is used in lightweight, recyclable soft drink bottles, as fibres in clothing, as a filling for anoraks and duvets, in car tyre cords and conveyor belts. It can also be made into a film that is used in video and audio tapes and x-ray films.
