Conductive Inks

Since 1990, Tekra has partnered with world class science and engineering pioneer, DuPont Microcircuit Materials (MCM) as an authorized distributor for DuPont MCM conductive inks (a.k.a. polymer thick films compositions, or "PTF"). Our association provides customers collaborative technical support encompassing the full range of conductive ink material compositions.

The Tekra / DuPont MCM partnership delivers value to our customers in many ways including: product recommendations, custom inventory programs, product innovations through application development, and unparalleled technical support.

Tekra carries a wide variety of conductive inks that add value to diverse markets including:

  • Membrane switches
  • Automotive
  • Biomedical sensors
  • Flexible displays
  • RFID antennae
  • Touch sensors

These functional compositions can be used to form conductive traces, capacitor or resistor elements, biosensors and dielectric and encapsulating layers. All conductive ink technologies are compatible with many processing techniques (e.g. screen print, flexo, gravure, etc.), on substrate surfaces ranging from polyester to glass.

Compositions available:

  • conductive silver ink
  • conductive carbon ink
  • silver silver chloride ink
  • dielectric ink

Only Tekra can provide material solutions for electrically conductive inks from DuPont MCM, and high performance PET and PEN films from DuPont Teijin Films™.
