ST-1950 Phase Change Heat Transfer Sheet
Product Introduction
- The ST1950, a high thermal conductivity phase change material (PCM) in the 1900 series, is available in both pad and phase change sheet configurations. Designed to reduce interfacial thermal resistance, it has passed reliability tests while maintaining superior performance. This material demonstrates excellent interfacial wettability across typical operating temperature ranges, resulting in extremely low surface contact resistance.
The working principle of phase change materials:
● At room temperature, the thermally conductive phase change material remains solid and cannot expel air from the interface.
● As the temperature rises, the phase-change thermal conductive material softens progressively, expelling the air from the interface, and the temperature subsequently decreases.
● When the phase-change thermal conductive material reaches its phase transition temperature, it transforms into a liquid state, effectively wetting the interface, expelling air from the interface, reducing thermal resistance, and maximizing heat transfer. When the equipment is not in operation, the material reverts to a solid state while maintaining 100% wetting of the interface.
