Descrizione generale

Itaconic anhydride (ITA) is a biobased material that is obtained from renewable resources. It is produced from the pyrolysis of citric acid or by fermenting carbohydrates which forms itanoic acid. Itanoic acid can be dehydrated to form an anhydride. It is relatively more reactive that maleic anhydride and can be used as an alternating monomer that facilitates the introduction of polar functionalities in polymers.[1][2]

Applicazioni

ITA can be copolymerized with methacrylate terminated poly(lactic acid) (PLA) for potential usage in packaging and biomedical applications.[3] It can also facilitate the production of reactive polyesters which can be used as starting materials in telechelics, cross-linking agents and macromonomers.[4]

Innovative Materials for Glass Ionomer Cements (GICs): Dental Applications

Innovation in dental restorative materials is driven by the need for biocompatible and natural-appearing restoration alternatives. Conventional dental materials like amalgam and composite resins have inherent disadvantages.

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
