Product Description

PTM5000 is Honeywell's thermally conductive phase change material in pad form. Admittedly it is the most effective, all around solution in Honeywell's phase change portfolio. It is designed to minimize thermal resistance at interfaces and maintain extremely stable performance through reliability testing required for long product life applications.

PTM5000 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. Clamping pressure and temperature are suggested to achieve a minimum bondline thickness for the best performance. All information for Thermal impedance is collected after the product is fully phase changed and without a shim.

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
Electrical Properties
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
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
