3M™ 5589H Thermally Conductive Acrylic Interface Pad

3M™ Thermally Conductive Acrylic Interface Pad 5589H is a soft acrylic based pad designed to provide a preferential heat transfer path away from heat generating components. Because of its softness, 3M Interface Pad 5589H can decrease the load to integrated circuit chips during compression, and provides good tack to many surfaces. These properties lead to a high performance non-silicone based thermal pad.
