Description

BERGQUIST® SIL PAD® TSP 3500 is a high-performance thermal interface material designed for applications that require both efficient heat dissipation and electrical insulation. With a thermal conductivity of 3.5 W/m·K, it provides exceptional heat transfer, making it an excellent choice for power electronics, motor controls, and aerospace applications. This silicone elastomer-based material is reinforced with fiberglass, ensuring superior mechanical strength, cut-through resistance, and long-term durability. Unlike thermal greases, which can be messy and require reapplication, the SIL PAD® TSP 3500 offers a clean, grease-free solution that simplifies installation and improves reliability over time.

In addition to its thermal efficiency, this material also provides excellent dielectric properties, with a breakdown voltage of 4,000 VAC, ensuring strong electrical insulation for sensitive components. It meets UL 94 V-0 flammability standards, making it a safe and reliable choice for demanding industries like automotive, industrial automation, and aerospace electronics. Its conformability ensures optimal surface contact, reducing thermal resistance and enhancing overall system performance. Whether used in power supplies, semiconductor devices, or motor drives, the SIL PAD® TSP 3500 is engineered to enhance longevity, improve efficiency, and ensure safe operation in high-performance electronic applications.
