T-pcm™ FSF-52
Thixotropic, Low Thermal Resistance, Wax Based Phase Change Material
T-pcm™ FSF-52, formerly known as Thermaphase®, is a wax-based self supporting film. It contains no substrate. At temperatures greater than 52 °C, T-pcm™ FSF-52 changes into a molten state, wets the heat sink and component surfaces to create a very thin, low thermal resistance interface.
T-pcm™ FSF-52 is thixotropic and doesn't flow from the interface.
T-pcm™ FSF-52 is available as individual die cut parts, kiss cut parts on rolls or sheets and uncut rolls. T-pcm™ FSF-52 has a thickness of 0.005” (0.125mm) and available with or without adhesive.
