General description

Polyvinylpyrrolidone (PVP), also commercially known as K30, is a water soluble polymer. It has a hygroscopic nature with good adhesive properties. It has a stable pH and has the ability to form transparent films.[1][2]

Application

PVP has a wide range of usage such as:
  • an adhesive for making gluesticks and metal adhesives[3]
  • a dispersant for ceramics[4]
  • coatings and inks[5]
  • formation of synthetic fibres and textiles[6][7]
  • porous membranes[8]

Other Notes

Polyvinylpyrrolidone is a component of Denhardt′s Solution and is included at a concentration of 1% (w/v) in the standard 50X stock solution.

Questions

1–4 of 4 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.
      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

  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

  3. What's the purity and residual monomer content?

    1 answer

    1. The purity is not a determined test specification for this product. However, the residual monomer content is located on the lot specific Certificate of Analysis.

      Please navigate to the DOCUMENTATION section of the product detail page to access a certificate under ‘Certificate of Analysis’: https://www.sigmaaldrich.com/product/sial/81420#product-documentation

  4. What is the average molecular weight of PVP K 30?

    1 answer

    1. The PVP K30 has a K-Value (1% w/v aqueous solution) of 29 - 32. The calculated molecular weight of Polyvinylpyrrolidone at K-30 is approximately 40,000 daltons. Historically, an average molecular weight of 58,000 daltons has been determined by light scattering.
