Creative Materials’ carbon inks and adhesives play an increasing role in applications including printed resistors, polymer thick film circuitry, membrane switches, electrical attachments, heaters, and static elimination. We can configure carbon inks to obtain a range of electrical conductivity values by blending them with silver inks and adjust conductivity to a specific level. Creative Materials can also blend carbon inks with silver inks to reduce cost for some applications.

Carbon inks are lubricious, providing low friction and excellent thermal stability. They are also chemically inert, with low reactivity to solvents and other chemicals. Our carbon inks can be applied by screen-printing, dipping, and syringe dispensing and feature excellent adhesion to Kapton, Mylar, glass and a variety of other substrates. Unlike conventional conductive materials, carbon inks are very resistant to abrasion, scratching, flexing and creasing.

Creative Materials’ waterborne carbon inks are environmentally friendly, while offering the same characteristics of high printability and varying electrical conductivity as our solvent-based carbon inks.
