General description

A tunable, polymeric, photonic material.
Poly(4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene)(AF2400) is a fluorinated polymer that formed by copolymerization of 4,5-difluoro-2,2-(trifluoromethyl)-1,3-dioxole(PDD) and tetrafluoroethylene(TFE). It has a relatively high glass transition temperature(Tg) and optical transparency which allows it be a photo-stable polymer that can be used for a wide range of coating application in electronic and electrochemical industry.

Application

Optically transparent due to the cycloether moieties in the structure which prevent crystallization. Also possesses nonadhesive characteristics and low refractive index making it more interesting than PTFE for optical applications.
Optoelectronic devices for optical clarity, low-refractive index coating for optical devices, protective coating for chemical resistance, release coating, and sight window for harsh chemical environments.
Used as a fluoropolymer for 157-nm lithography.
AF2400 dissolved in supercritical CO2 as a solvent can be used as an activated layer that forms an electrode for fuel cell applications. It may be used in the fabrication of organic nanofiltration membrane with polytetrafluoroethylene(PTFE) that can be used in the extraction of hexane from crude mixture of soybean oil. Nanocomposites of silver nanoparticles(AgNPs) may be formed by incorporating AF2400 via vapour phase co-deposition process that can be used in surface enhanced raman spectroscopy sensors and color filters.

Features and Benefits

High gas permeability, high compressibility, good creep resistance, low thermal conductivity, transparent to microwaves and the lowest dielectric constant of any known fluoropolymer.

Physical form

Amorphous copolymer.

Questions

1–2 of 2 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. 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
