I hope someone knowledgeable could enlighten me about the following - I'm doing a report on plastics and need help figuring out some of the details. Thanks in advance!
What is the difference between polyester and polymer - is polyester a type of polymer or is it made from polymer or something else?
Is PET a type of polyester? Or is polyester a different product made from the same source? (I've noticed polyester is used - or referred to
- in products such as apparel, whereas PET ıs in particle form and used in making bottles).
What are TPA and DMT? Are they exclusively used for making PET - or are they used in producing other polyester products, as well? (Is DMT or TPA used in making a polyester fleece, for example?)
Thanks!
