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.
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.
Polyester film capacitors are film capacitors using a dielectric made of the thermoplastic polar polymer material polyethylene terephthalate (PET), trade names Hostaphan or Mylar, from the polyester family. They are manufactured both as metallized wound and stacked versions, as well as film/foil types.
Metallized film capacitors towards capacitive energy storage at elevated temperatures and electric field extremes call for high-temperature polymer dielectrics with high glass transition temperature (Tg), large bandgap (Eg), and concurrently excellent self-healing ability.
Especially for applications with high current pulse loads or high AC loads in electrical systems, heavy-duty film capacitors, here called "power capacitors", are available with dielectric ratings of several kilovolts. But the manufacture of film capacitors does have a critical dependency on the materials supply chain.
Polymer capacitor usually operate under multi-field coupling conditions, such as high temperature and high electric field, which can alter the microstructure of polymer dielectric films.
