General description

Poly(vinyl acetate) (PVAc) is a non-crystalline, atactic polymer. It is prepared from vinylacetate monomer via free radical polymerization. It is commonly usedin the food industry due to its low toxicity and excellent flexibility. PVAc films are used as emission sensors forvehicles and in oral drug delivery products.

Application

Poly(vinyl acetate) can be used as a:
  • Starting material to prepare polymer fibers for gas and humidity sensor applications. Citric acid-doped PVAc nanofibrous mats can be used to develop sensors for trimethylamine gas at room temperature.
  • Polymer coating for floating tablets showing a controlled drug delivery. PVAc is a suitable excipient to ensure reliable and safe drug release. PVAc-based matrix tablet flow due to intrinsic low density and high elasticity of polyvinyl acetate coating.
It can also be used to prepare cellulose nanofibrils(CNF)-PVAc nanocomposite adhesives by simple mixing of CNFs suspension with PVAc and polyvinyl alcohol solution. The addition of CNFs enhances the mechanical properties of the nanocomposite.

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.
