Application

PMMA/HA (Hydroxyapatite) composites have be used in biomedical applications such as dentistry, orthopedic retainers, and bone replacement. It has been used as substrate for graphene growth.[1]
Some studies report its use as
PMMA-titania hybrid optical thins films[2]
PMMA/polystryrene/clay nanocomposites[3]
PMMA/polyurethane/carbon black nanocomposites for methanol fuel cells.

General description

Poly (methyl methacrylate) (PMMA) is an amorphous transparent thermoplastic polymer. PMMA is recognized as an optical polymer based on its refractive index of 1.49. Hence, it is used in optical fibers.[2]It finds uses in biological applications because of its low water absorption capability and biocompatible.The maximum moisture content of PMMA is 1.71% and SBF absorption is 1.96%.Simulated Body fluid test (SBF) is a method to characterize the in vitro bioactivity of ceramic materials, by immersing the materials in an aqueous SBF solution.

Questions

1–5 of 5 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/418/501/product-dating-information-06-25-mk.pdf

  2. What is the average size of PMMA beads, in product 182265, poly (methyl methacrylate)? (in nm or micrometre)? Are they 100 nm or 200 nm or 1 micrometre?

    1 answer

    1. Unfortunately, the product is not tested for particle size so there is no information that can be shared.

      Helpful?

  3. 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
