But to a polymer scientist with her molecular weight, there’s a huge difference. In fact, according to Resource Recycling, “When they’re processed together, PETG melts and becomes sticky while PET remains solid. This feature sets … But what about different types of resins? In addition, advocates of the bill have stated that they open to working with Eastman and the Plastics Industry Association to create a new resin code for PETG, so it can be more easily recycled in its own stream – another possible solution. Required fields are marked *. With just this one addition, the chemical composition is completely changed, creating a whole new plastic. While opponents of the bill such Eastman Chemical Co. and the Plastics Industry Association, agree that there is an issue when PET and PETG are mixed in the recycling stream, they claim that instead of changing the labeling and creating a double standard, technology already exists to adjust the sensitivity of the sorter at the beginning of the recycling process to differentiate between PET and PETG. by Ravi Toor | Mar 26, 2019 | Uncategorised | 1 comment.

PET, PETE, RPET, PETG Plastic. PLA is naturally derived from cornstarch.
