RS PRO Phase Change Interface Material

RS PRO phase change materials are ideal for thermal management applications. Available in this range are phase change interface materials in sheets, resistor pads and as a dispensable paste.

Phase change materials work because they change their state with changes in temperature between the heat source and the heatsink. During this process, the material stores thermal energy which is then released as the material cools. This means that the material can absorb thermal energy as the heat is generated which helps to keep the desired component cool. This improves contact between the surfaces, completely fillling air gaps and increasing heat transfer.

How do thermal pads work?
By keeping the internal components of electronic products from wear and tear resulting from high circuit board temperatures, thermal pads help to provide extended longevity. They’re also important in providing safety by eliminating the possibility of electrical fires. Thermal pads are soft and comfortable, which helps to provide vibration and shock damping to minimise potential damage to components. They’re manufactured in a variety of standard thicknesses and dimensions but can also be custom fabricated to fit various applications.

RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards; they’re only given the RS PRO seal of approval if we’re confident of their exceptional quality, which means you can be confident too.
