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.

General description
Application
- Lanthanide-complex grafted poly(methyl methacrylate-co-maleic anhydride) copolymer. These luminescent polymers exhibit high thermal stability and can be used as luminous layers for optoelectronic devices.[4]
- Poly (methyl methacrylate) (PMMA), is a common material used in the production of lenses for concentrating photovoltaic (CPV) modules.
- Polymethyl methacrylate, methyl methacrylate crosspolymer, and methyl methacrylate/glycol dimethacrylate crosspolymers. These polymers are used in cosmetic surgery, dentistry, and joint replacement.[5]
- Poly (methyl methacrylate) (PMMA)-based personalized medical devices.[1]
- Interpenetrating methyl methacrylate-based polymeric networks with enhanced thermal and mechanical properties.
- Poly(methyl methacrylate-co-hydroxyethyl methacrylate) (PMMA-co-PHEMA) copolymers by emulsion copolymerization. These copolymers form thermooxidatively stable and ductile films.
- Poly(methyl methacrylate) nanoparticles through differential microemulsion polymerization.

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
