Honeywell PTM7950 SP Super Highly Thermally Conductive PCM Pad

Honeywell PTM7950 Super Highly Thermally Conductive Phase Change Material (PCM) Paste Thermal Interface Materials

Honeywell’s PTM7950 series, a super highly thermally conductive Phase Change Material (PCM) in both pad and paste formats, is designed to minimize thermal resistance at interfaces, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost.

Based on a novel polymer PCM system, this material exhibits excellent interface wetability during typical operating temperature ranges, resulting in extremely low surface contact resistance.

A proprietary material provides superior reliability (pass 150°C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance (<0.04°Ccm2/W @ no shim), making the PTM7950 series desirable for high performance integrated circuit devices.
