Thermal phase change material

EMP 2019 Electronics Manufacturing & Production Handbook Manufacturing / Production Technology, Hardware & Services

Included in Electrolube’s thermal management product portfolio are TPM350 and TPM550 thermally conductive phase change materials.

TPM350 has a thermal conductivity of 3,5 W/m.K and becomes workable at approximately 50°C. At this ‘activation’ temperature it changes state to become a lower viscosity material, minimising contact thermal resistance and improving thermal conductivity. Once it cools, it reverts back to its original state. The material’s advanced formulation ensures minimal contact thermal resistance.

TPM550 has a higher thermal conductivity of 5,5 W/m.K and an activation temperature of 45°C. In common with the TPM350 product, TPM550 produces no mess due to its thixotropic characteristics which prevent flow outside of defined interfaces. Both TPM350 and TPM550 can be reworked and their low specific gravity means that more applications can be served per kilogram of the materials, reducing production costs.

The new phase change materials are silicone-free, have an operating temperature range of -40°C to +125°C and are RoHS-2 compliant.
