Application: Capacitor Polypropylene Film for Type M-PP/ S-PP ( 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.
Application Scope
M-PP: Mainly for metallized-film capacitor.
S-PP: Mainly for foil-film capacitor.
