Tpcm™ 5000 Thermal Phase Change Material

Tpcm™ 5000 is a new high-performance TIM in the Laird product offering. Tpcm™ 5000 is designed to provide the best performance at the price available. Tpcm™ 5000 provides very low thermal resistance by coupling high thermal conductivity of 5.3 W/mK, minimal bondline thickness, and with superior wetting of the mating surfaces. Softening between 50°C - 70°C, the initial pad thickness can decrease to a bondline as thin as 25µm. Tpcm™ 5000 reliability has been demonstrated through exposure to 1,000 hours of various aging tests resulting in proven dependability at an operating temperature of 125°C. The specialty polymeric matrix offers superior pump-out resistance when compared to thermally conductive greases and other phase-change materials. Tpcm™ 5000 has been formulated to provide just the right tack, remaining on liners yet easily removable for application.
