Capacitor Polypropylene film(the biggest manufacturer in the world) M-PP/S-PP:Mainly for metallized-film capacitor(4um--12um ) 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.
