High Signal Fidelity at High Frequencies
High frequency connectivity is a critical enabler of SDGs related to work, quality education, public safety and health and well-being.
Preserving signal fidelity at higher frequencies (5G service and beyond) requires new technology and innovative materials to tackle unique challenges related to telecommunications infrastructure and devices, such as mobile phones. For example, today’s mobile phones have multiple antennas to send and receive signals across many frequencies to support 3G, 4G and 5G service. 5G antennas must not only minimize signal losses but must fit into a compact footprint within the phone, where space for the display and battery are prioritized. Furthermore, technology that manages electromagnetic interference (EMI) is needed to prevent cross-talk to antenna materials.
In today’s high-performance electronic devices, data consumption continues to stretch the limits across a variety of end-market segments, including healthcare, telecommunications, military, industrial and aerospace. High-speed, high frequency signal transfer across the telecommunications networks creates many circumstances in which signal fidelity can be compromised, resulting in unreliable service for customers who depend upon their devices. Such challenges need to be met in a way that maintains device affordability (e.g. enabling high manufacturing yields) and enables designers to deliver the mobile phone features consumers want.
DuPont’s Pyralux® polyimide laminate solutions tackle the dual challenges of delivering high signal fidelity at high frequencies (over 6GHz) while significantly improving manufacturing yields, reducing industrial waste, transitioning to lower footprint materials and lower manufacturing costs.
Continuous innovation by our engineers and scientists also includes transitioning to recycled copper foil for a lower footprint. These actions with our DuPont Pyralux® product line deliver superior performance combined with improved sustainability.
DuPont has long been a market leader in laminates for flexible and rigid-flex PCBs. Our extensive family of Pyralux®, Interra® and Temprion® branded products expands possibilities for flexible laminates, embedded passives and thermal performance in demanding applications such as 5G networks, electric vehicles, and consumer electronics.

Compared to traditional antenna materials, the superior performance of DuPont Pyralux® improves as frequencies increase, enabling telecommunications innovations to advance a connected society.
BLUEDGE™ Polymeric Flame Retardant Technology eliminates the use of hazardous flame retardants with one that has inherently low toxicity, delivers required performance and is economically viable.
DuPont materials for advanced chip fabrication enable faster and more complex computing for smartphones and other electronic devices, while consuming less power per bit.
Sorek B, which leverages DuPont FilmTec™ membranes, will increase Israel's desalination capacity by 35% and set a new benchmark for efficiency, sustainability and a record low price of water through desalination.
Reduction of packaging waste is an increasingly important topic for the healthcare industry as it seeks to achieve a circular economy. Packaging for IV sets presents a unique design challenge because of the variety of structural components, the durability required and the need for more sustainable options.
In 2021, in line with our Innovating Safer by Design and Enabling a Circular Economy objectives, the Asia CMP Center implemented a strategy to reduce its production of halogen waste by selecting raw materials with a less hazardous chemical profile, and cooperating with local recycling technology companies to reuse, recycle, and regenerate the byproduct.
Reverse osmosis (RO) water treatment systems provide the finest levels of pressurized crossflow filtration but can require a significant amount of cleaning to combat biofouling that results in operational challenges. Biofouling is the deposition of micro- and macro-organisms on industrial cooling equipment. Unchecked, biofouling causes significant operational and economic problems.
Moving to a “dry” running conveyor belt system in the bottling industry will reduce maintenance down time and amount of wastewater than requires proper disposal. DuPont and Regina have developed an innovative conveyor solution that reduces energy consumption and extends useful life.
