Metallized Polyester Film



Feature:

By adopting the design of electrician homo-polypropylene with ultra-high purity, the film is made by biaxial extended through a flat membrane process. It features good thickness and uniformity and high mechanical strength. The winded capacitors take on the characteristics of low dielectric dissipation and high insulation resistance.



Application scope:

M-PET: Mainly for Metallized film capacitors

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-PP:Mainly for metallized-Film Capacitor. S-PP:Mainly for foil-film capacitor.
