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.

Application
- Chemical modification of polypropylene by maleic anhydride: This study explored the application of maleic anhydride (MAH) for modifying the properties of polypropylene through melt grafting. The findings reveal how variations in the concentration of MAH influence the polymer′s properties (Ebadi-Dehaghani et al., 2014).
- Renewable production of phthalic anhydride: A study on the synthesis of phthalic anhydride from biomass-derived furan and maleic anhydride, highlighting an eco-friendly pathway for producing a widely used industrial chemical (Mahmoud et al., 2014).
- Enhancement of biopolymer properties: Research on using maleic anhydride as a compatibilizer in natural fiber-reinforced poly(lactic acid) composites, which demonstrates the improvements in mechanical and thermal properties of the composites (Yu et al., 2014).
- Application in electrical property enhancement: This article reports on the application of maleic anhydride grafted polypropylene which significantly enhances the material′s electrical properties, potentially applicable in various advanced electronics and engineering fields (Zhou et al., 2016).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
