Aplicación

  • Characterization of low-density polyethylene and LDPE-based/ethylene-vinyl acetate with medium content of vinyl acetate: This study characterizes the effects of vinyl acetate content on the properties of low-density polyethylene and EVA composites, highlighting the impact on material performance (Pham, 2021).
  • The thermo-mechanical degradation of ethylene vinyl acetate used as a solar panel adhesive and encapsulant: This research investigates the degradation mechanisms of ethylene vinyl acetate when used in solar panel applications, providing insights into its durability and performance under environmental stress (Badiee et al., 2016).
  • Recent development of ethylene–vinyl acetate modified asphalt: This article explores the use of ethylene-vinyl acetate in modifying asphalt binders, focusing on the improvements in road material technologies due to changes in vinyl acetate content (He et al., 2023).

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.
