Tpcm™ 900 Thermal Phase Change Material
Tpcm™ 900 is a high-performance, non-electrically conductive phase change material. At 50°C, Tpcm™ 900 begins to soften and flow, filling the microscopic irregularities of both the thermal solution and the component's surfaces, thereby reducing thermal resistance. Tpcm™ 900 is a flexible solid at room temperature and freestanding without reinforcing components that reduce thermal performance.
Tpcm™ 900 shows no thermal performance degradation after 1,000 hours @130°C, or after 500 cycles, from -25°C to 125°C. The material softens and does not fully change state resulting in minimal migration (pump out) at operating temperatures (see viscosity curve). Tpcm™ 900 is supplied in rolls with top tabbed liners for easy manual or large volume automatic application. Individually die cut parts can also be supplied.
- Naturally tacky at room temperature, no adhesive required
- No heatsink preheating required
