DuPont Microcircuit Materials (DuPont) is launching electronic inks that cure quickly at low temperatures, expanding the possibility of printing electronics onto an entirely new group of plastic films. The technology is expected to enable electronic components such as sensors, heaters and antennas to be printed on more versatile and less expensive substrates.
"This really opens new doors for application designers," said Kerry Adams, segment manager, DuPont Microcircuit Materials. "As DuPont continues to expand its portfolio of advanced materials to meet the needs of the printed electronics market, we continue to look for ways to offer cost savings and the potential to put electronics into almost any device."
Historically, electronic inks have required curing temperatures between 100°C and 140°C restricting electronic substrates to those that can survive at high temperatures. The new DuPont™ PE827 and PE828 low-temperature inks cure at as low as 60°C, opening up the possibility for printed electronics designers to use less expensive plastic films. By expanding substrate choices, the possibility for implementing printed electronics in new applications continues to grow. Potential applications could include printed antennas, sensor applications, heated surfaces and smart packaging applications.
Substrates that are now viable options for printed electronics include PVC, polystyrene, high-density polyethylene, and acrylic polymers, among others.
DuPont Microcircuit Materials (MCM) is a leading innovator and high-volume supplier of electronic inks and pastes that offers a broad range of printed electronic materials commercially available today. The growing portfolio of DuPont MCM electronic inks is used in many applications, including forming conductive traces, capacitor and resistor elements, and dielectric and encapsulating layers that are compatible with many substrate surfaces including polymer, glass and ceramic.
MCM has over 40 years of experience in the development, manufacture, sale and support of specialized thick film compositions for a variety of electronic applications in the consumer electronics, automotive, photovoltaic, biomedical, military and telecommunications markets.
