What materials are used in capacitors?
The three dielectric materials widely available and used in capacitors are oil, kraft paper and polypropylene film. Capacitors using an oil-impregnated kraft paper as insulation and a separate metal film system are an older design which results in higher heat losses. These higher losses are due to the paper properties as an insulator.
