Honeywell PTM7950 SP Super Highly Thermally Conductive PCM Pad

Honeywell PTM7950 Phase Change Thermal Pad is the best-performing thermal material in the world, based on our in-house testing. It works perfectly for CPUs and GPUs. Using PTM7950 along with Honeywell TGP8000PT Thermal Putty offers an unmatchable result!

PTM7950 is designed especially for high-performance chips requiring exceptional thermal performance, durability, and reliability. Nvidia and Lenovo have already been using PTM7950 for their top-of-the-line flagship GPUs and gaming laptops.

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 wettability 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.
