Honeywell PTM7950 Thermal Pad Phase Change Material CPU GPU Computer Watercooler 0.2 0.25mm Heatsink 40x40 40x80 8.5W/Mk

Product Description
PTM-7950 is a super highly thermally conductive Phase Change Material (PCM) in both pad and paste formats. It is designed to minimize thermal resistance at interfaces, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost.


PTM-7950, based on a novel polymer PCM system, exhibits excellent interface wetability during typical operating temperature ranges, resulting in extremely low surface contact resistance. Since PTM-7950 comes only in 0.20mm/ 0.25mm (thicker versions are under development) you need to be sure that this thickness is compatible and suitable for the flatness of your package.


PTM-7950 is a proprietary material that provides superior reliability (pass 150C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance (<0.04Ccm2/W @ no shim), making the PTM-7950 series desirable for high performance integrated circuit devices.
Product Use
The material must go through the phase change temperature to exhibit entitlement performance.
