General description

Silicone oil is low viscosity liquid polymerized siloxanes with organic side chains.[1]

Application

Low viscosity silicone oil has been used to prepare cellulose based electrorheological particles for medical devices.[2][3] The diffusive behavior of spreading of a silicone oil polymer on solid surfaces was studied.[4] It was also used to investigate Marangoni flow, induced by two liquid droplets on a solid surface, exposed in air.[5] Many diverse applications of silicone oil are as heat exchangers, hydrophobic coating of glass, ceramics, textiles and leathers, component of salves.[1]

Questions

1–3 of 3 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. Do you have data on the vapor pressure of 5 and 10 cst silicone oil over a range of temperatures?

    1 answer

    1. Unfortunately, the vapor pressure over temperature hasn't been tested for 5 or 10 cSt silicone oil (P/N# 317667 and 378321).
