Phase Change Materials

TMATE 2900 Series

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 50°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 @130°C or after 500 cycles from -25°C to 125°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).

• 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

• Available in 3 thicknesses, 0.005″, 0.010″ and 0.020″ (0.125mm, 0.25mm and 0.50mm)

Additional Product Description Standard Thicknesses:
0.005” (0.13 mm) 0.010” (0.25 mm) 0.020” (0.51 mm) Consult the factory for alternate thicknessesStandard Sheet Sizes:
9” x 9” (229 mm x 229 mm)
Tmate™ 2900 sheets are supplied with a clear polyester top liner to protect phase change material.
