Biaxial orientierte Folie für die Herstellung von Keramikkondensatoren

摘要

The invention relates to the use of a multilayered film as a support film for producing a ceramic capacitor. Said multilayered film consists of a base layer and at least one cover layer (A), this cover layer (A) containing a propylene polymer and at least one incompatible polyolefin. Said incompatible polyolefin is an LDPE, HDPE, MDPE, ethylene-propylene-copolymer, cycloolefin polymer or syndiotactic polymer. The surface of the cover layer (A) is rougher than the surface of the film facing it and the film is provided with a ceramic coating on its smoother surface. This coating is dried and then separated from the support film.
