5589H

Technical Data November 2013 3M Thermally Conductive Acrylic Interface Pad 5589H Product Description 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. Good softness and conformability to non-flat surfaces. Excellent compressive stress relaxation. High thermal conductivity. UL94 V-O certified (File No. E176845). Good surface tack leads to low thermal resistance at surface. Non-silicone acrylic elastomer. Good dielectric performance. Excellent durability for long term thermal conductivity and electric insulation stability.
