BOPP-Folie für einen Kondensator

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.Applications: The film is speciallyused for capacitors after metalizing.Technical Characteristics typical value Unit Typical Values Test conditions Tensile strenghMD MPa 140 Stretching speed:100/min@23,50r.h. .
