Technical Data September 2014 3M™ Thermally Conductive Silicone Interface Pads 5591 and 5591S Product Description 3M™ Thermally Conductive Silicone Interface Pad 5591 and 5591S are highly conformable, slightly tacky silicone elastomer pads. These interface pads are designed to provide heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. Features and Benefits • Good thermal stability of the base polymer with excellent softness of the thermal pad. • Good thermal conductivity in an ultra soft silicone polymer base. • The product tack is such that a mechanical means to support the pad in a final assembly is required.
