DuPont Unveils Pyralux ML Laminate Series, Offering High Thermal Management for Extreme Environments

DuPont Pyralux ML Laminate Series
Written by Kirsten Campbell

DuPont introduced the DuPont™ Pyralux® ML Series of double-sided metal-clad laminates, a unique addition to its extensive family of Pyralux® laminates for flexible and rigid-flex printed circuit boards (PCBs). Developed for optimal thermal management, these laminates are an ideal solution for high-reliability markets such as aerospace, defense, electric vehicles (EVs), artificial intelligence (AI)-related networking and other electronic devices. The Pyralux® ML laminate series provides exceptional performance in challenging environments, making it a versatile and innovative solution for many different applications.

Laminates serve as the backbone for complex circuits built on both rigid and flexible substrates. They provide mechanical integrity to flex circuits while allowing designers the freedom to fit circuits into the available footprint. The Pyralux® ML double-sided metal-clad laminates have been engineered to address the challenges of thermal management and provide optimized performance and are ideally suited for flexible printed circuits, sensors, heaters, and thermocouples deployed in high-reliability applications that can benefit from unique metals with advanced material performance.

Unlike other Pyralux® products, the Pyralux® ML laminate contains metal alloy, such as copper-nickel (CuNi), featuring Kapton® all-polyimide dielectric technology. The alloys provide essential thermal resistance for heating, thermal conductivity to improve the desired heat transfer, resistivity for higher heat output, and thermoelectric properties as needed for the application. Pyralux® ML laminates are available in a variety of dielectric and foil types, thicknesses, and a range of metal constructions. The laminates are fully compatible with most conventional circuit fabrication processes, making them a versatile product-development option for OEMs, designers and fabricators. Pyralux® ML double-side clads are currently supplied in sheet form and are being strategically rolled out by DuPont Electronics & Industrial.

“At DuPont, we understand the critical role that laminates play in supporting the complex circuits required by our customers. With the launch of Pyralux® ML, we’re proud to add another innovative solution to our extensive family of laminates,” said Thean Ming Tan, global business director, Laminate Products, DuPont Interconnect Solutions. “Our relentless focus on optimizing thermal management and advanced material performance is driven by the evolving needs of industries such as aerospace, defense, and industrial applications with high-performance, high-reliability requirements. As leaders in materials science and engineering, we’re committed to developing new products and applications that push the boundaries of what’s possible, and we’re honored to be a part of such a vital industry.”

“Heightened demand for robust thermal-management capabilities was the impetus for DuPont to leverage our engineering expertise in creating this unique laminate material, which is not available elsewhere,” stated Richard Wessel, applications technology manager, DuPont Interconnect Solutions. “While fabricators have been assembling laminates using base materials with similar properties, the consistent appearance, strong bond strength, and predictable performance of the Pyralux® brand are key benefits for customers that choose Pyralux ML®.”
