Carbon Paste (140°C, 50 ohm/sqr/25µm)
Thermoplastic carbon paste that can be printed in one piece on a single screen is a cutting-edge material with multiple uses in the energy and electronics industries. This carbon-based material provides excellent conductivity, thermal stability, and printability. Developed using advanced research and production methods, it addresses the increasing demand for high-performance conductive materials. To achieve a sheet resistance of 50 Ω/sqr/25µm, the paste must be dried at a low temperature of 140°C. Printed structures should be processed for 30 to 60 minutes at 140°C in a convection oven.
