What Makes Laird Performance Materials a Crucial Component in Modern Electronics

 

As the electronics industry continues to push the limits of performance, speed, and miniaturization, the role of advanced materials becomes more critical than ever. One name that stands out in this arena is Laird Performance Materials—a global leader in engineered solutions for thermal management, electromagnetic interference (EMI) shielding, and signal integrity. But what exactly makes Laird’s offerings essential in today’s electronic applications?

Understanding Laird Performance Materials

Laird Performance Materials, now part of DuPont, has built a legacy of innovation by designing highly customized materials for complex electronic environments. These materials are engineered to protect sensitive electronic components from thermal damage, EMI, and mechanical stress—all of which can compromise performance and reliability in high-frequency and high-speed systems.

Whether used in 5G antennas, automotive control units, smartphones, or power electronics, Laird products are integrated silently but critically within the system architecture.

Why Are These Materials So Vital in Electronics?

Modern electronics are denser, faster, and hotter. Microcontrollers, microprocessors, and high-speed memory chips generate heat that needs to be dissipated efficiently. At the same time, these devices operate at radio frequencies (RF), exposing them to EMI, which can distort or entirely disrupt signals. To ensure operational efficiency, durability, and safety, manufacturers rely heavily on advanced shielding and thermal interface materials (TIMs)—two of Laird’s specialties.

Key Technologies Offered by Laird Performance Materials

Let’s explore the main product lines that make Laird a trusted name in high-performance electronics manufacturing:

• Thermal Interface Materials (TIMs)

TIMs are used to transfer heat from critical components to heat sinks or spreaders. Laird’s TIMs include gap fillers, thermal pads, phase change materials, and greases, each engineered for specific applications and operating conditions.

Applications:

• Heat dissipation in LED drivers, automotive ECUs, and power amplifiers

• Maintaining consistent thermal conductivity in server systems and graphic processing units (GPUs)

• EMI Shielding Solutions

EMI shielding is a major concern in densely packed electronic assemblies where interference from neighboring components can cause malfunction. Laird's shielding products include:

• Board-level shielding cans

• Conductive elastomers

• Microwave absorbers

These solutions are used extensively in RF modules, telecommunications infrastructure, and military-grade electronics.

• RF and Microwave Absorbers

Laird’s absorbers are tailored for high-frequency and millimeter-wave applications, which are key in radar systems, automotive LiDAR, and 5G communication devices. These materials suppress electromagnetic waves by absorbing rather than reflecting them, thereby reducing system noise and cross-talk.

• Ferrite Products

Ferrites are used to suppress electromagnetic interference in power and signal lines. Laird offers various types of ferrite cores and beads, which are especially useful in:

• Cable assemblies

• Printed circuit boards (PCBs)

• Switch-mode power supplies (SMPS)

• Thermal Management Solutions for Battery Packs

As electric vehicles (EVs) and renewable energy storage systems grow in popularity, managing the temperature of lithium-ion battery cells becomes a safety-critical concern. Laird provides custom thermal barriers and passive cooling materials that maintain the optimal performance of battery management systems.

Industrial and Sector Applications

Laird’s product lines aren’t confined to one sector—they’re cross-functional and tailored for use across various electronics industries:

• Automotive Electronics

• ADAS (Advanced Driver Assistance Systems)

• Battery thermal management

• High-speed infotainment systems

• Consumer Electronics

• Smartphones and tablets

• Wearable technology

• Smart home devices

• Industrial Equipment

• Robotics

• Automation controllers

• Heavy-duty communication relays

• Networking and Telecommunications

• 5G base stations

The Growing Demand in the Electronics Market

With the ongoing evolution of technologies like IoT, 5G, AI-enabled systems, and autonomous vehicles, the demand for thermal and EMI shielding materials is surging. As engineers design increasingly miniaturized devices packed with powerful processors, the margin for thermal and signal error shrinks—making Laird’s solutions not only desirable but essential.

Moreover, emerging electronics applications in medical wearables, edge computing, and smart factories further underline the importance of materials that can cope with challenging electrical and thermal conditions.
