PTM 6000 | Phase Change Pad
- Higher reliability than PTM5000
- 3.5 - 4.5 Thermal Conductivity
- Pad form
Product Description
PTM6000 has almost identical properties to PTM5000 but it is a higher reliability version . It 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. It can withstand temperatures up to 150°C.
PTM6000 has a Thermal conductivity of 3.5 - 4.5 (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. The proprietary material provides superior reliability and maintains low thermal impedance (0.06-0.08) , making it desirable for high-performance integrated circuit devices.

General Properties | |
Specific Gravity Specific Gravity Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless. | 2.3 |
Thickness range | 0.20 - 1.00 mm |

Volume Resistivity Volume Resistivity Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface. | 2.1x1014 Ohms⋅cm |
Thermal Properties | |
Specific Heat Capacity Specific Heat Capacity Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property. It is also an example of an extensive property since its value is proportional to the size of the system being examined. | 0.97 J/g.K J/(g⋅°C) |
Thermal Conductivity Thermal Conductivity Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system. | 3.5 - 4.5 W/m.K |
Thermal Impedance | 0.06 - 0.08 °C·cm²/W |
