Description générale

Silicone oil is a liquid based siloxane that is part of the methyl silicone fluid system. It has a viscosity of 500 cSt that is dependent on the chain length distribution. Its refractive index is ~ 1.402 and dielectric strength is ~ 14 kV/mm. It′s surface tension tends to increase with an increase in the viscosity. [1]

Application

Silicone oil can be used for a variety of application such as: heat transferring medium in chemical and petrochemical industries, a dielectric coolant, a lubricant and antiflatulent agent[1], protective coatings for construction materials[2], a cosmetic additive.[3]

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. How do you measure the viscosties of your products? especially, silicone oils. which instrument or method do you use?

    1 answer

    1. The method to determine viscosity is product specific. For this product (378380) the supplier reports viscosity by Brookfield method.
