Polypropylene film capacitors are often used in applications in which negligible discharge rates are required, because of their high insulation resistance (IR) and low conduction current, or leakage current (LC).
the availability of film processing technology, which allows its production on an industrial scale. the ability to be processed to very thin films (downgauging) in order to achieve a high volume efficiency in the capacitor, while keeping adequate tensile strength. Polypropylene films down to about 1.9 μm are commercially available.
A broad study of the performance of a modern polypropylene capacitor film is therefore warranted to serve as a baseline for further materials development, and to demonstrate the capability of BOPP films to withstand electrical stresses unrealistic for almost any other type of insulation.
Polymers in Film Capacitors - The Next Generation Material is available! Polypropylene is the polymer of choice for most film capacitors, but there is an inherent high temperature limit for its usage. New polymer materials are therefore required to overcome these temperature limitations.
Over the history of film capacitors, from a material perspective, the major breakthrough started with the move from paper to polymers, and especially to polypropylene, which finally became the dominant dielectric in film capacitors today.
As figure 12 shows, in polypropylene capacitors (PP MKP, MFP), the capacitance remains vir-tually unaffected by frequency up to 1 MHz. In polyester capacitors (PET MKT) and especially in PEN capacitors (polyethylene naphthalate, MKN), the effect of frequency is more noticeable:

Polypropylene Film. Polypropylene Film (PP) is the most widely used film for AC capacitors, including power factor capacitors. It is also used for stack capacitors and ''naked'' capacitors due to low moisture absorption. Its main advantage is its low loss factor and better capacitance stability compared with PET film. Advantages of PP film are:
