12um bopp film for capacitor
1> Advantages
* * * Better electrical conductivity, compared with Zn/ Al film
* * * Considerable good self-healing performance
* * * Good performance of anti-air-corrosion.

* * * Convenience for reserve and long storage time
2> Disadvantages
* * * higher capacitance loss than Al/ Zn film
* * * coated lay is very thin, so metallikon is difficult.
* * * In time of metal spraying, alumina will increase the resistivity.
3> Application

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.

Capacitor Polypropylene Rough Film Type RPP/ RRPP ( 6um --18um)
