Description
Universal Science™ UniPhase™ 2500 is a phase changing thermal interface material and is supplied as a dry compound coated onto a Kapton® MT substrate, formulated to function as a superb alternative to messy and inconsistent thermal grease, it also delivers consistent and reliable thermal performance.
UniPhase™ will flow at a phase change temperature of 60°C and conform to the differing surface textures between a heatsink and device, once the material exceeds the phase change temperature the compound becomes thixotropic and paste-like in consistency.
In combination with device mounting pressure and phase change flow, UniPhase® expels air voids at the interface helping to reduce thermal resistance. UniPhase® can be die-cut to suit a wide variety of electronic applications such as DC/DC power converters and is typically between any heat dissipating electrically isolated component and heatsink.
Benefits
- Delivers a consistent and reliable thermal interface
- Mounting pressures and phase change flow expels air between uneven surfaces reducing thermal impedance
- Delivers a thin bond line between surfaces helping to improve thermal performance
Features
- Dry compound coated onto a Kapton™ MT substrate
- Offers high dielectric strength and cut-through resistance alongside efficient heat transfer
- Delivers a highly reliable and consistent thermal interface for demanding applications
Recommended Uses
- Typically used to thermally connect an electrically isolated heat generating component to a heatsink
- Within an application to replace thermal grease
- Power supplies and power modules
