Polyethylene Terephthalate (PET)
Polyethylene terephthalate, PET for short, is a plastic used to make bottles, many food-grade plastic wrap and packaging solutions and transparent films for LCD screens and other optical devices. It also has medical applications, such as the manufacture of plastics for synthetic ligaments and prosthetic cardiac devices. PET is recyclable and is used to make textile fibers such as polar fleece. Chemically, PET is a polymer of terephthalic acid ester and ethylene glycol.
