Phase Change Material (PCM)

PCM respectively Phase Change Material is a wax based thermally conductive material. It begins to melt and flow at temperatures between 45°C and 55°C. It is available in different material thicknesses 

Phase Change Material to compensate smallest unevennesses

Our phase change material is based on wax, is solid as delivered and begins to flow at temperatures between 50°C and 60°C. This compensates for microscopic unevenness between the heat source and heat sink and ensures optimal heat transfer resistance. Standard material thicknesses are: 0.05 / 0.13 / 0.20 / 0.25 / 0.30 / 0.35 / 0.40 / 0.45 / 0.50 mm.

Material thicknesses and delivery forms Phase Change Material

The phase change material of our TCPC series is naturally adhesive, flexible and very easy to use. The material is available in material thicknesses from 0.05 to 0.5 mm, in various colors and in various delivery forms, such as standard plates with 400x300 mm or customer-specific punched parts. More details can be found in our product specifications and in our data sheets.

Why are PCMs important for electronic components?

Electronic components depend on good heat transfer towards cooling components, as they are sensitive to overheating. As soon as the Phase Change Material reaches its phase change temperature and liquefies, surface roughness is compensated and air inclusions are expelled, which improves surface contact and enables increased heat exchange. Thermally conductive Phase Change Material is therefore an ideal substitute for thermal pastes. The most common applications are notebooks, desktop CPUs and IGBT units.
