TGPK27B is a light blue coloured, thermally conductive phase change (PCM) material. It is a solid at room temperature but changes phase at 55℃; which allows it to wet surfaces. TGPK27B is supplied in an easy to use format so that it can be manually applied to a wide range of surfaces. The unique formulation gives and exceptionally low thermal resistance for heat transfer in the most demanding of applications.
FEATURES
- Designed to maximize heat sink performance and improve component reliability
- Displaces entrapped air between power-dissipating electronic components
- Bond Line Thickness (BLT) of 0.0254mm
- Practically no thermal contact resistance due to a very small thermal resistance path
- Solid at room temperature for ease of application
- Consistently and cleanly applied as dry pads to a heat sink or component surface
- Resistant to dry out and pump out
