Capacitor Polypropylene film for M-PP/S-PP
Features
By adopting the imported super high-purity capacitor-grade home-polypropylene resin, the film is made by biaxial-orientation tenter process. The film features excellent profile evenness, high BDV and high mechanical strength. The winded capacitors take on the characteristics of low dielectric dissipation and high insulation resistance.
Application scope
M-PPMainly for metallized-film capacitor.
S-PPMainly for foil-film capacitor.
