一般描述

硅油是一种低粘度，液体聚合，有有机侧链的硅氧烷。硅油具有抗菌活性，能够抵抗体外微生物引起的眼内炎。[1]
硅油构成一组疏水性聚合物化合物，具有硅氧烷重复单元（–Si–O）的线性链和各种侧链。由于其独特的性能，如润湿性、润滑性、平滑滑动行为和机械强度，它们被广泛用于电绝缘体、消泡剂、实验室和润滑剂。

应用

硅油可以作为眼内液体用于玻璃体视网膜手术，因为它可以维持视网膜和视网膜色素上皮之间的粘附。

它可以在两相分配生物反应器中用于处理气体流出物。硅油与水相相容，并在两相之间形成更好的乳液。

它还可以用于在玻璃表面生成疏水涂层。(4)

特点和优势

  • 高扩展功率
  • 无毒
  • 高润滑性
  • 形成稳定的薄膜条
  • 好的稳定性

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
