June 2016–Creative Materials has introduced two new products that offer superior electrical performance when compared to other conductive and resistive inks: 126-33 is a new silver-filled electrically conductive ink, and 126-28 is a low-resistance carbon ink. Typical applications include biomedical applications, biosensors, electronic component manufacturing, RFID antennas, EMI/RFI shielding of polyimide flexible circuits, polymer thick film circuitry, membrane switches, printed heaters, and resistive elements/coatings.

The conductivity rating of 126-33 is 0.008 Ω /square/mil (sheet resistivity), with a volume resistance of 0.00002 Ω-cm. Competitor inks typically have sheet resistivity of 0.01 Ω /square/mil. The superior conductivity of this product allows the end-user to print narrower and/or longer circuit trace lines or thinner coatings without compromising overall maximum ohm values. The proper use of this feature can result in a significant cost saving or enhanced performance.

The 126-28 has sheet resistivity of 8 ohms/square/mil, which favorably compares with other resistive inks, which are in the 20 ohms/square/mil range. Lower resistance can also allow for narrow print lines or thinner coatings, which consistently results in reduced cost.

Both products feature excellent adhesion to polyester, polyimide and a wide variety of high-energy surfaces. In addition, both inks offer excellent abrasion and chemical resistance, as well as excellent long-term aging. These inks can be applied by screen-printing, dipping, or syringe dispensing, and they cure at temperatures as low as 110°C.
