General description

Copper foil with a thickness of 0.25 mm and a 99.98% trace metals basis is a top-quality product that has numerous industrial and commercial applications. It is produced using cutting-edge manufacturing processes that ensure superior quality and consistency. The foil is carefully inspected to meet the specified purity level and is free from any imperfections like scratches, dents, and tears. Copper foil is a highly versatile material that offers outstanding electrical conductivity, thermal conductivity, and corrosion resistance.

Application

Copper foil is commonly used in a variety of applications such as printed circuit boards (PCBs), electromagnetic shielding, and as a substrate in chemical vapor deposition. The 0.25 mm thickness of this foil makes it suitable for many applications, providing sufficient strength and durability while remaining easy to handle and manipulate. The 99.98% trace metals basis ensures that the copper foil is of the highest quality, with only minimal levels of impurities like lead, arsenic, and bismuth. This level of purity is critical for many industrial applications, particularly those in the electronics industry, where even small amounts of impurities can significantly impact the performance and reliability of the end product.

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-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
