Tpcm HP105 Series

For Exceptionally Low Thermal Resistance

The Tpcm™ HP105 Series is a high-performance phase change material (PCM) product with
exceptionally low thermal resistance.

It has a softening range of approximately 50°C to 60°C. Proprietary technology prevents
excessive pump-out after the initial heat cycle. The material is naturally tacky and requires no
adhesive coating or heat sink preheat for attachment.

The Tpcm HP105 Series does not cure and can be easily removed without pulling the
processor out of the socket. It is supplied in rolls with a top tabbed liner for easy manual
or large volume automated applications

• Softening range of 50°C to 60°C
