Overview

For Exceptionally Low Thermal Resistance

The Tpcm 580 Series is a high-performance thermal phase change material (PCM) designed
to meet the thermal reliability and price requirements of high-end thermal applications.
The Series is inherently tacky, flexible and exceptionally easy-to-use. The Tpcm 580 Series is
available in four thicknesses: 0.003” (Tpcm 583), 0.005” (Tpcm 585), 0.008” (Tpcm 588),
0.010” (Tpcm 5810) and 0.016” (Tpcm 5816).

 

At temperatures above its transition temperature of 50°C (122°F), the Tpcm 580 Series
begins to soften and flow, filling the microscopic irregularities of the components it comes
into contact with. The result is an interface with minimal thermal contact resistance. Due to
the gradual change in viscosity (softening), it minimizes migration (pump-out).

 

The Tpcm 580 Series can be supplied as cut parts in strips and rolls with top tabbed liners for
easy application. The top tabbed liner can be removed immediately or provide a protective
cover during shipping, and can be removed at assembly. It can also be supplied in sheets and
custom die-cut configurations; and meets all environmental requirements including RoHS.

STANDARD PACKAGING Sheets: 9” x 9” (228.6 mm x 228.6 mm) 18” x 18” (457.2 mm x 457.2 mm) Cut Parts: On strip with top tabbed liner Individual cut through
