1. Product Overview

BERGQUIST BOND PLY TBP 800 is a thermally conductive, fiberglass-reinforced, pressure-sensitive adhesive tape designed for thermal management applications. It provides high bond strength, electrical isolation, and thermal transfer while eliminating the need for mechanical fasteners or heat-cure adhesives.

Key Features & Benefits:

  • Thermal impedance: 0.6°C-in²/W @ 50 psi
  • High bond strength to most epoxies and metals
  • Double-sided, pressure-sensitive adhesive tape
  • Electrically isolating and flame retardant (UL 94 V-0)
  • Cost-effective alternative to screws, clips, and heat-cure adhesives
  • Operating temperature range: -40 to 125°C

2. Applications

  • Mounting LED assemblies to troffer housing and heat sinks
  • Attaching heat spreaders to power converter PCBs or motor control PCBs
  • Securing heat sinks to BGA graphic processors or drive processors
