Product Description
Tflex™ HD90500 is a 3500 um configuration within the Tflex™ HD90000 Series, a high-performance silicone thermal gap filler engineered for applications requiring efficient heat transfer and low mechanical stress on sensitive electronic components. The ceramic-filled silicone construction provides typical thermal conductivity of 7.5 W/m·K while maintaining high compliance for effective contact across uneven mating surfaces. Naturally tacky surfaces support placement during assembly without requiring an additional adhesive coating.
Key features
- 7.5 W/m·K thermal conductivity for demanding electronics cooling applications.
- Highly compliant silicone construction helps minimize stress while conforming to uneven surfaces.
- Naturally tacky surfaces simplify installation without an additional adhesive layer.
Applications / Suitable for
- Automotive electronics and ADAS modules
- High-performance computing and networking equipment
- Industrial power electronics
- Telecommunications infrastructure
