Features By adopting the imported super high-purity capacitor-grade homo-polypropylene resin, the rough film is produced by biaxial-orientation tenter process. The film features excellent physical and electrical properties, such as good profile evenness, high electric strength, low dielectric dissipation and good windability etc. The film can company with a good many kinds of capacitor impregnation oil well. According to the authentication from National Power Capacitor Test Center, the product conforms to all the requirements of capacitor insulation materials. Application range: Mainly for power, electrothermal and other relevant kinds of high voltage capacitors designed as foil-film or foil-film & paper with oil-impregnation.
