Is polyethylene terephthalate a petrochemical?
Polyethylene terephthalate (PET) is the most important commercial polyester polymer. In the United States and Canada over 4 billion pounds per year are produced from petrochemical feedstocks. PET also forms a clear polymer so it is also used in films such as Mylar, as well as in photographic films and transparencies.
