Patent number: 8378047Abstract: The present technology relates to a biaxially oriented polypropylene film. The biaxially oriented polypropylene film comprises a polypropylene material having xylene solubles of at least 0.5 percent by weight. The polypropylene also has a strain hardening index of at least 0.15 measured at a deformation rate d?/dt of 1.00 s?1 at a temperature of 180° C. In certain embodiments, the strain hardening index is defined as the slope of a logarithm to the basis 10 of a tensile stress growth function as a function of a logarithm to the basis 10 of a Hencky strain for the range of Hencky strains between 1 and 3.Type: GrantFiled: January 9, 2009Date of Patent: February 19, 2013Assignee: Borealis Technology OYInventors: Manfred Stadlbauer, Eberhard Ernst, Petri Lehmus, Yvo Daniels, Franck Jacobs

Patent number: 7914899Abstract: Certain embodiments of the present technology provide a capacitor film comprising a polypropylene material. The capacitor film comprises xylene solubles of at least 0.5 percent by weight. In certain embodiments the xylene solubles are in a range of 0.5 to 1.5 percent by weight. The film also comprises a crystalline fraction melting in the temperature range of 200° C. to 105° C. determined by stepwise isothermal segregation technique. The crystalline fraction comprises a part, the part representing at least 10 percent by weight of said crystalline fraction, and wherein the part melts at a melting rate of 10° C./min. Certain embodiments present a capacitor film where the part melts at or below 140° C. In other embodiments, the said part melts at or below the temperature T=Tm?3° C., wherein Tm is the melting temperature of the capacitor film and/or the polypropylene material, and the part represents at least 45 percent by weight of the crystalline fraction.Type: GrantFiled: January 8, 2009Date of Patent: March 29, 2011Assignee: Borealis Technology OyInventors: Manfred Stadlbauer, Eberhard Ernst, Lauri Huhtanen, Yvo Daniels, Franck Jacobs

Publication number: 20110040061Abstract: A short-chain-branched polypropylene having xylene solubles of at least 0.5 percent by weight is provided. In certain embodiments the polypropylene has a strain hardening index of at least 0.15 as measured by a deformation rate of 1.00 s?1 at a temperature of 180° C. In certain embodiments, the strain hardening index is defined as the slope of the logarithm to the basis 10 of the tensile stress growth function as function of the logarithm to the basis 10 of the Hencky strain for the range of the Hencky strains between 1 and 3. The polypropylene may have xylene solubles in the range of 0.5 to 1.5 percent by weight. In certain embodiments, the polypropylene has a strain hardening index in the range of 0.15 to 0.30. In certain embodiments, the polypropylene has a melting point of at least 148° C.Type: ApplicationFiled: October 28, 2010Publication date: February 17, 2011Applicant: BOREALIS TECHNOLOGY OYInventors: Manfred Stadlbauer, Eberhard Ernst, Lauri Huhtanen, Yvo Daniels, Franck Jacobs
