PTM7950 is a highly thermally conductive Phase Change Material (PCM) that lasts longer and is more effective than tradiational thermal paste Size 31x50x0.2mm, Phase change at 45°C, Thermal Conductivity: 8.5 W/m.K, It is normal for it to melt at high temperatures.It achieves good heat dissipation performance through repeated melting and solidification. Note: it requires operational skills, recommended to use under the guidance of professionals PTM7950 is a proprietary material that provides superior reliability (pass 150C baking 1000 hours, T/C-B 1000 cycles) maintains low thermal impedance (
