Due to it's thermal stability, exceptional flatness and insulation properties, polyester film is a good substrate for printed circuits and other electronic applications.

HiFi offers an extensive range of polyester films for use in a variety of electronic applications.


Polyester film is recommended for applications where circuits are not exposed to hostile environmental conditions. Where enhanced environmental resistance is required, we recommend DuPont Teonex® PEN films (polyethylene naphthalate) which has higher perfomance at elevated temperatures.
