PTM7000 is designed to minimize thermal resistance at interfaces and maintain extremely stable performance through reliability testing required for long product life applications. As with all Phase change materials, it has stable Thermal Impedance across accelerated aging tests and does not display bleed, pump or flow out. PTM7XXX product line has the highest Thermal conductivity and lowest thermal impedance out of the entire PTM Series
PTM7000 has a Thermal conductivity of 6.5 (W/m·K) depending on the bondline thickness and is based on a robust polymer PCM structure that exhibits excellent wetting properties during typical operating temperature ranges, resulting in very low surface contact resistance. This proprietary material provides superior reliability and maintains low thermal impedance (0.06) , making it desirable for high-performance integrated circuit devices.
Please keep in mind that 7XXX is a Product Series. Base 7000 performs on the baseline of the stated properties while PTM7900 and PTM7950 are the highest performing materials of this product line reaching 8.5 W/m·K and 0.04 TI.
