General description

Pyromellitic dianhydride is a dianhydride class of monomers commonly used in the preparation of polyimides polymers which are used in aerospace, electronics, and automotive industries because of their excellent thermal stability, high mechanical strength, and inherent flame resistance. It is also used in the synthesis of thermoplastic polymers such as polyesters and polyethers, as well as plasticizers and epoxy resins. Additionally, PMDA serves as a curing agent for epoxy resins. Epoxy resins are widely used in adhesives, coatings, composites, and electrical insulation materials.

Pyromellitic dianhydride (PMDA) is an acidic anhydride that can be used as a repair agent and as a chain extender in the formation of polyethylene terephthalate (PET) based chain extensions. It is mainly used in the production of thermoplastics and other coating applications.[1][2]

Application

PMDA can be used as:
  • A monomer to synthesize aromatic polyimides with excellent thermo-mechanical and chemical properties. These polymers find the applications in automotive and electronic industries.
  • A capping agent in the development of siloxane-based hybrid materials for potential usage in organic electronics.
  • A monomer in the preparation and modification of thin film composite membranes, which are used in water purification, gas separation, and biomedical devices.
  • A monomer in the synthesis of pyromellitic diimide-based copolymers as stable cathode active materials for lithium and sodium-ion batteries.

Questions

1–2 of 2 Questions  

  1. 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.

  2. 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
