  • Patent number: 11851552
    Abstract: The present invention is directed to a biaxially oriented polypropylene (BOPP) film with improved breakdown strength and to a capacitor comprising an insulation film comprising a layer of the biaxially oriented polypropylene film of the present invention. The present invention is further directed to a process for producing a biaxially oriented polypropylene film. Finally, the present invention is further directed to the use of a biaxially oriented polypropylene film of the present invention as layer of an insulation film of a capacitor. The BOPP film comprises a polypropylene composition, wherein the polypropylene composition comprises a high isotactic homopolymer of propylene and a polymeric ?-nucleating agent. The BOPP film has a dielectric breakdown field strength Eb63.2 of at least 595 kV/mm.

  • Patent number: 5942180
    Abstract: A method and apparatus for heating fiber reinforced thermoplastics in sheet form in contact heating means, in which the thermoplastic is heated between bands in the space between two heating means which can be pressed against it and is at the same time held between an upper and a lower sheet-like or filament-shaped restraining means, which is respectively arranged between the thermoplastic and the band. After heating up, the thermoplastic is taken out of the heating zone together with the restraining means and bands, the bands firstly being detached from the thermoplastic, while the restraining means continue to bear against the thermoplastic, and subsequently the restraining means are detached from the thermoplastic.
