About 99% of these are capacitors, 1% are insulation materials & elements, and 1% are plastic film. All film capacitors use a thin plastic film as the dielectric (or insulator), but what separates each capacitor type is the material used as the dielectric. The main specification advantage of polystyrene is its low dielectric absorption, which only really shows up in professional instrumentation-type sample-and-hold applications. My favourites, and the most expensive, are the yellow LCR metalised polypropylene axial (tubular) types. Polystyrene was developed by a German apothecary in 1839 from the resin of the American sweet gum tree.
