Thermal Interface Phase Change Material

Created to perform when the heat is on

Thermal Interface Phase Change Material
  • High thermal conductivity
  • High performance
  • Easy to apply
  • Changes state once ‘activated’

Electrolube phase change materials are specialist high performance thermal interface materials which are easily applied via screen printing. During use, the temperature of the device increases until it reaches the ‘phase-change’ temperature. The material then changes state (phase change) back to a more traditional paste improving thermal conductivity.

Phase change materials are materials that change state from solid form to liquid and back again. The solid material absorbs heat until it reaches its softening point, whereby it reverts back to a softer material with fluid-like characteristics, conforming to the contours of the interface and ensuring the most efficient heat transfer. This process is particularly useful as a thermal management technique and Electrolube have developed a specialist range designed specifically as thermal interface materials. The ‘activated’ phase change material has exceptionally high thermal conductivity, dissipating heat away from the electronic components to the heatsink or other cooling device.

We would advise that you test any product you select thoroughly, as each application will vary from the next and figures quoted on a TDS may not match the results in the ‘real’ operating environment.

TPM550 is one of Electrolube's latest high-performance thermal interface material innovations. It is a phase change material meaning that when it reaches its 'activation' temperature of 45°C it changes state to become a lower viscosity material, minimizing the contact thermal resistance and improving the thermal conductivity. Once it cools, it reverts back to its original state.

It is easy to apply via screen and stencil printing, containing a small amount of solvent which evaporates once it has been applied to partially cure the material in place. This eliminates the mess associated with thermal pastes or greases while maintaining workability.

The phase change allows for a vast array of application scenarios while it also has an exceptional thermal conductivity value of 5.5W/m.K. maintaining high performance through a wide operating temperature range.

With thermal interface materials, every application is different and one should not rely solely on the TDS to compare products. If you have any concerns or questions, please don't hesitate to get in touch with our technical support team.
