  • Method of manufacturing film for film capacitor and film for film capacitor
    Patent number: 9005500
    Abstract: When extrusion of a molten resin by means of an extruder is started, a simple polyetherimide resin is melt extruded from a lip portion 7a of a T-die 7, and a film of the simple polyetherimide resin is molded. The molding material is then switched to a resin composition including the polyetherimide resin and a fluorine resin and then a film of the resin composition is continuously extruded and molded from the T-die 7. Having been covered with a very thin film 8a of the simple polyetherimide resin, on a flow passage face of the lip portion 7a of the T-die 7, a resin composition layer 8b including a polyetherimide resin and a fluorine resin, which has affinity with the film 8a, is then formed at a center part.
    Type: Grant

  • Method for manufacturing resin film for thin film-capacitor and the film therefor
    Patent number: 8524133
    Abstract: The present invention provides a method for manufacturing a film for a film capacitor making it possible to produce a film for a film capacitor which has a thickness of 10 ?m or less and which is excellent in a heat resistance and a voltage resistance at a high thickness accuracy by using a polyetherimide resin and provides as well a film for a film capacitor.
