  • Weatherable multilayer film
    Publication number: 20070166562
    Abstract: A multilayer polymer film includes first and second polymer layers. The first polymer layer includes a first ultraviolet radiation absorber. The second polymer layer overlies the first polymer layer and includes a second ultraviolet radiation absorber. The first ultraviolet radiation absorber has a peak absorbtivity wavelength less than 300 nm and the second ultraviolet radiation absorber has a peak absorbtivity wavelength greater than 300 nm.

  • Draw resonant resistant multilayer films
    Publication number: 20050186431
    Abstract: The disclosure is directed to a multilayer film including a first layer and a second layer. The first layer has a fluorinated polymer. The second layer has a melt strain-hardening component and forms no more than about 30% by volume of the multilayer film.

  • Draw resonance resistant multilayer films
    Publication number: 20050186432
    Abstract: Aspects of the invention are found in a multilayer film comprising a first polymer layer and a second polymer layer. The first polymer layer comprises a blend of a first fluoropolymer having a first average molecular weight and a second fluoropolymer having a second average molecular weight. The first average molecular weight is greater than the second average molecular weight.

  • Low extractable, thermoplastic syringe and tip cap
    Publication number: 20050075611
    Abstract: A prefilled syringe and syringe assembly having a syringe and a tip cap are produced from materials that do not interfere with the substance contained in the syringe and enable long term storage. The tip cap is made from a blend of a cyclic olefin polymer or copolymer and a thermoplastic elastomer. The thermoplastic elastomer is blended with the cyclic olefin copolymer in an amount so that the normally stiff and hard cyclic olefin copolymer is flexible and resilient to effectively seal and couple to the tip of a prefilled syringe.
