General description
Bis(2-hydroxyethyl) terephthalate belongs to the class of monomers known as diols or glycols. It is widely used to synthesize unsaturated polyester resins, polyethylene terephthalate (PET), and new biocompatible polymer systems. BHET can also be used as a plasticizer in polyester resins and rigid or flexible polyurethanes. Additionally, BHET and its derivatives have also been investigated for their potential use in biomedical applications, including drug delivery and tissue engineering, due to their excellent biocompatibility and mechanical properties.
Application
Bis(2-hydroxyethyl) terephthalate canbe used as a monomer to prepare biodegradable aromatic-aliphatic copolyestersfor sustainable flexible packaging applications. The incorporation of BHET as abuilding block offers a promising approach to enhancing the properties ofbiodegradable plastics and promoting sustainable packaging solutions.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
