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.

Aplicación
- Polymer Physics behind the Gel-Spinning of UHMWPE Fibers: Though indirectly related, the study′s focus on material science can be paralleled with research on paraffin oil′s role in polymer processing and synthesis, especially in contexts where its lubricating properties are critical to the manufacturing processes (Wang et al., 2024).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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

What is the carbon chain length in paraffin oil and paraffin wax?
1 answer-
The carbon chain length is not determined on the paraffin oil and wax products. According to Freund et al. (1982) the melting point is directly correlated to the chain length. The melting point of this product as well as most other paraffin products is not tested. See the link below for a graphic that may be of interest:
