Phase Change Thermal Pad
Phase Change Thermal Pads effectively fill air gaps and voids between mating surfaces, replacing trapped air between heat-generating electronic components and heat sinks. At room temperature, the material remains solid and easy to handle, making it ideal for use as a thermal interface pad. When the operating temperature reaches its phase-change temperature, the material softens and begins to flow, conforming to and filling microscopic irregularities on the contacting surfaces. This creates an interface with an ultra-thin bond line thickness and reduced thermal contact resistance, enabling more efficient heat transfer.Phase Change Thermal Pads are available in sheet, roll, and custom die-cut configurations.
