Tmate 2900

Thermal Phase Change Material

Product Description

For Exceptionally Low Thermal Resistance The Tmate 2900 Series is a reusable phase change material (PCM) designed for ease of testing and rework ability. It has a composite construction of a special malleable metal alloy and a high-performance PCM. At 50deg C the Tmate 2900 Series begins to soften and flow filling the microscopic irregularities of the thermal solution thus reducing thermal resistance. It shows no thermal performance degradation after 1 000 hours @130deg C or after 500 cycles from -25deg C to 125deg C. The PCM softens and does not fully change state resulting in minimal migration (pump-out) at operating temperatures (see viscosity curve). It is available in three thicknesses: 0.005""; (0.125 mm) 0.010""; (0.25 mm) and 0.020""; (0.5 mm).

Features and Benefits
  • Low thermal resistance at low pressures
  • Reusable: make and break thermal interface connection many times
  • Naturally tacky at room temperature, no adhesive required
  • No heat sink preheating required
