3M™ Thermally Conductive Silicone Interface Pad 5583S is designed to provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders, or other cooling devices. 3M pad 5583S consists of highly conformable and slightly tacky silicone elastomeric sheet filled with thermally conductive ceramic particles that provide enhanced thermal conductivity and excellent electrical insulation performance. 3M pad 5583S has permanent polyester film 12 µm think on one side to provide for a non-tacky surface, increased puncture resistance, ease of handling and rework.
