一般描述

聚(甲基丙烯酸甲酯)（PMMA）是一种无定形透明热塑性聚合物。PMMA的折射率为1.49，被认为是一种光学聚合物。因此，它被用于光纤中。[1]由于它具有较低的吸水能力和生物相容性，因此，它被用于生物应用中。[2]PMMA的最大含水量为1.71%，SBF吸收率为1.96%。模拟体液（SBF）测试方法通过将陶瓷材料浸入SBF水溶液中来鉴定材料的体外生物活性。

应用

PMMA可以用作石墨烯生长的基质。[3][4]已有研究报道了将其用作
  • PMMA-二氧化钛杂化光学薄膜[1]
  • PMMA/聚苯乙烯/粘土纳米复合材料[5]
  • 用于甲醇燃料电池的PMMA/聚氨酯/碳黑纳米复合材料
  • 丙烯酸玻璃
  • 外科中的植入物
  • 作为垫片。[6]

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
