Description

A type of polyester made by condensing ethylene glycol and terephthalic acid. In 1951, polyethylene terephthalate (PET) became the first commercially marketed polyester. It was sold as Dacron® in the U.S. and as Terylene in Great Britain. PET is extremely durable and dimensionally stable. It is resistant to abrasion, chemicals. PET is used to make Mylar® and other strong moisture-resistant films used in packaging, photographs, x-rays and audio/visual tapes. Since 1977, PET has been widely used in food containers, especially for carbonated beverages. Recycled PET is used as fiberfill and in cast resins, such as boat hulls and shower units.
