  • Publication number: 20160020466
    Abstract: The invention relates to a dispersion comprising a dispersion medium, a polymeric dispersing agent, and carbon nanotubes dispersed in the dispersion medium. The proportion of carbon nanotubes present in the form of agglomerates with an average agglomerate size of >=1 [mu]m to the total quantity of carbon nanotubes <=10 vol %, and >=70% of the carbon nanotubes which are not present in the agglomerated form have a length of >=200 nm. the invention further relates to a method for producing such a dispersion, to a method for producing an electrode with the dispersion, to an electrode obtained in this manner, and to an electrochemical element containing the electrode.

  • Patent number: 7980358
    Abstract: The invention relates to a lightweight sound insulating lining (1) for a body component of a motor vehicle, in particular in the form of a lightweight front wall lining, comprising a sound absorbing layer, a sound insulating layer which is directly connected to the sound absorbing layer and substantially air tight, as well as an adjoining foam layer (1.3), wherein the sound absorbing layer (1.1) is made of a porous absorber, preferably a fiber fleece or a foam, which has an air permeability in the range of 150 to 2000 liters/m2s at a test pressure of 100 Pa. The sound insulating layer (1.2) is formed by an integral skin layer of the foam layer (1.3) with a thickness of at least 0.5 mm, and is integrally joined to the porous absorber by back-foaming the porous absorber substantially without foam penetration therethrough. Furthermore, a method for manufacturing such a lining is disclosed.

  • Publication number: 20070078253
    Abstract: The present invention relates to soft sprayable polyurethane elastomers which exhibit low hardness without the addition of plasticizers. Other aspects of this invention are composites with a soft touch surface and processes of making these composites. These composites may also be decorative and/or pigmented composites.

  • Patent number: 6921000
    Abstract: This invention relates to an apparatus and a process for rapidly and accurately dispensing fluids, in which at least one component is dispensed into the reaction vessel in two or three stages. In this process, the amount of fluid dispensed in the second and third stages is determined on the basis of the mass flow rate calculated in the preceding sub-step.

  • Patent number: 6840124
    Abstract: Rapid and efficient production and examination of formulations for polyurethane foams using only small amounts of materials are achieved by allowing the foam-forming mixture to foam in a container, preparing disks from sections of the container in which the foam is present and removing a plurality of cylindrical samples having substantially the same density from the disk.
