PTM 5000 | Phase Change Pad

PTM5000 is Honeywell's thermally conductive phase change material in pad form. Admittedly it is the most effective, all around solution in Honeywell's phase change portfolio. It is designed to minimize thermal resistance at interfaces and maintain extremely stable performance through reliability testing required for long product life applications.

PTM5000 has a Thermal conductivity of 3.5 - 4.5 (W/m·K) depending on the bondline thickness and is based on a robust polymer PCM structure that exhibits excellent wetting properties during typical operating temperature ranges, resulting in very low surface contact resistance. The proprietary material provides superior reliability and maintains low thermal impedance (0.06-0.08) , making it desirable for high-performance integrated circuit devices. Clamping pressure and temperature are suggested to achieve a minimum bondline thickness for the best performance. All information for Thermal impedance is collected after the product is fully phase changed and without a shim.
