Flexible Electronics

A wide range of polyester film suitable to help all printable electronics requirements

Flexible Electronics

Optimum performance in electronic applications requires effective heat management.

Thermal stability is very important for a range of applications where any temperature related movement of the polyester film has the potential to cause problems with the printed circuit – for this reason we have made a large investment in a heat stabilisation line, able to produce polyester film with a 100 fold improvement in thermal stability compared to standard PET film, thus producing product suitable for virtually any application.  These range from; Membrane touch switches (MTS), flexible printed circuitry(FPC), RFID antennas, display applications and sensors.

We can also offer non-stabilised polyester films. These are more cost effective but still provide enhanced environmental resistance and tolerance to high temperatures.
