Flexible Circuits

DuPont Teijin Films manufactures a range of PET and PEN polyester films that are ideally suited for use in flexible circuitry applications, whether Flexible Printed Circuits (FPC) or Flat Flexible Cable (FFC):

• For use in copper laminates and adhesive overlays
• For applications including automobile systems such as dashboards and flat wiring solutions, heating systems, appliances, RFID tags and labels, smart card lead frames and antennae and many others

Mylar® and Melinex® PET polyester films offer significant advantages to manufacturers and users of flexible circuitry:

• Reliable and trusted performance proven over many years
• Robust solutions for a wide range of applications
• The ability to manufacture laminates without curl
• A range of dimensional stabilities tailored to your application needs

For more demanding circuitry applications our range of high performance Teonex® PEN polyester films offer:

• Resistance to selected soldering conditions for surface mount applications and attachment of connectors
• Superb hydrolysis resistance for use in applications where the circuit may get wet, for example automotive door wiring
• Enhanced temperature stability giving greater options for extending flat wiring into automotive engine compartments and similar applications
• Greater dimensional stability and higher barrier properties for cutting edge flexible electronics applications
