Phase Change Materials

PCM45F

PCM45F is a Phase Change Pad with a Thermal Impedance of 0.09 – 0.12 (°C cm²/w), Thermal Conductivity of 2 (w/mk) and Specific Gravity of 2.2 (g/cm³).

Overview
PCM45F is Honeywell's thermally conductive phase change pad. It is designed to minimize thermal resistance at interfaces and maintain extremely stable performance through reliability testing for long product life applications. In addition, it has excellent electrical properties and very high-volume resistivity.

PCM45F has a Thermal conductivity of 2.0 - 2.5 (W/m·K) depending on the bondline thickness. It 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 (0.09-0.12), making it desirable for high-performance integrated circuit devices.
