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.
This paper is divided into two parts: first, the capacitor film manufacturing technology is briefly outlined, and then, a comprehensive review of a modern capacitor-grade polypropylene film is given. Capacitor-grade BOPP film is made of highly isotactic polypropylene. The molecular structure of PP with higher isotacticity is more regular.
New polymer materials are therefore required to overcome these temperature limitations. Accordingly, a new class of engineering materials, EPN (Ethylene-Propylene-Norbornene), has been developed for capacitor films, combining the advantages of polypropylene and cyclic olefin copolymers.
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.
The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.
