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

一般說明
马来酸的结构由四个碳分子以及两端的羧酸基团组成,中心碳原子之间有一个双键。马来酸酐在其环状分子中具有五个原子,不饱和键在引发剂存在下经历自由基聚合。
應用
- 在高密度聚乙烯(HDPE)的接枝过程中,通过单体微胶囊化技术,可以将增强的功能和改进的性能引入聚合物中,用于功能涂层、膜或表面处理、粘合剂和涂层。
- 在聚乳酸(PLA)的功能化中,并在天然纤维生物复合材料中充当偶联剂。功能化改善了PLA和天然纤维之间的相容性和界面粘附,从而增强了所得到的生物复合材料的机械性能并扩大了其应用范围。
- 马来酸酐可用于合成不饱和聚酯树脂和用作合成重要产品的反应物,例如农业化学品、润滑剂添加剂,和食品酸化剂。

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.
