1. Product Overview

BERGQUIST LIQUI FORM TLF 6000HG is a thermally conductive, one-part, liquid formable gel designed for thermal management applications. This pre-cured, dispensable gel offers high thermal conductivity (6.0 W/m-K), excellent chemical and mechanical stability, and is suitable for narrow gaps (≤3mm) in telecom applications like 5G base stations.

  • Technology: Silicone
  • Appearance: Gray paste
  • Application Method: Dispense from cartridge
  • Operating Temperature Range: -60 to 200°C

2. Applications

  • Thermal interface for RRU, AAU, and BBU in telecom infrastructure
  • Filling gaps between heat-generating devices and heat sinks
  • Applications requiring low assembly pressure
  • High-value assemblies that require rework
