Frequently Asked Questions
It is a common thermoplastic polymer resin, used to make fibres for clothing, containers for liquids and foods, and many other products.
The term refers to a class of compounds. Some specific esters may have associated handling requirements, but the polymer PET is generally considered safe for food contact.
It is pronounced /ˌter.efˈθæl.eɪt/. The 'phth' is challenging; it's often said as 'ef-THAL-ate' after the 'tere' part.
It is highly unlikely. You would use common terms like 'PET plastic' or 'polyester' instead.
