General description

Poly(ethylene-co-vinyl acetate) (PEVA) is a flame-retardant material with good mechanical and physical properties. It is majorly used as an insulating material in wire and cable industry.[1][2]

Application

  • Correlation between Cohesive Energy Density, Fractional Free Volume, and Gas Transport Properties: This study explores the properties of EVA materials that affect their gas permeability, important for applications like packaging and barrier materials (Kubica & Wolinska-Grabczyk, 2015).
  • The Thermal and Mechanical Properties of EVA and its Crosslinked Analogues: This research investigates how crosslinking affects the thermal and mechanical properties of EVA, which could interest material scientists working with polymers (Wang & Deng, 2019).
  • Investigation of morphological, rheological, and mechanical properties of cyclic olefin copolymer/EVA blend films: This study focuses on the blend properties of EVA with other polymers, providing insights useful in academia and material science (Durmus et al., 2018).
  • Fabrication, characterization, and properties of EVA/magnetite nanocomposites: Relevant to material scientists, this research discusses the incorporation of magnetite nanoparticles into EVA for enhanced properties (Ramesan, 2014).

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
