It adopts imported polypropylene resin particles, which are biaxially stretched by flat film. It has the characteristics of good thickness uniformity, high mechanical strength and excellent electrical performance. Mainly used in metallized film capacitors, such as AC motor capacitors (AC motor capacitors), low-voltage parallel capacitors (low-voltage power capacitors), energy-saving lamps capacitors (energy-saving lamps capacitors), DC capacitors (DC capacitors), energy storage pulses DC filter capacitor (Energy storage, Pulsed, DC link filter capacitor), photovoltaic wind power capacitor (photovoltaic wind power cylinder capacitor), hybrid electric vehicle capacitor (capacitors for hybdid cars), etc. Regular thickness 2.0um-12um
