Product Uses
3M™ Thermally Conductive Silicone Interface Pad 5516S is designed to provide a preferential heat transfer path between heat-generating components and heat sinks, heat spreaders or other cooling devices.
The soft and conformable silicone elastomer construction helps accommodate uneven and non-flat surfaces while maintaining good contact across the thermal interface.
The thermally conductive ceramic filler provides approximately 3.1 W/m-K thermal conductivity, while the material also provides good electrical insulation for electronic thermal management applications.
The 5516S version incorporates a thin polymeric film carrier that improves handling. Its non-tacky surface also supports easier re-work during assembly.
The 230mm × 320mm × 0.5mm sheet format is suitable for thermal interface components, electronic assemblies, LED applications, PCB thermal management and custom die-cut thermal interface solutions.
