| 20090131611 | SHORT-CHAIN BRANCHED POLYPROPYLENE - 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 | 05-21-2009 |
| 20090148716 | ELECTRICAL INSULATION FILM - 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. | 06-11-2009 |
| 20090149612 | BIAXIALLY ORIENTED POLYPROPYLENE FILM - 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 dε/dt of 1.00 s | 06-11-2009 |
| 20100047544 | BIAXIALLY ORIENTED ELECTRICAL INSULATING FILM - The invention relates to a biaxially oriented electrical insulating film which contains a mixture from a polypropylene P1 and a polypropylene P2 which is different therefrom. The polypropylene P1 is a linear polypropylene and has an Mw/Mn> | 02-25-2010 |
| 20110040061 | SHORT-CHAIN BRANCHED POLYPROPYLENE - 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 | 02-17-2011 |
