Technical Data September, 2010 3M Thermally Conductive Adhesive Transfer Tapes 9882 9885 9890 Product Description 3M Thermally Conductive Adhesive Transfer Tapes 9882, 9885, and 9890 are designed to provide a preferential heat- transfer path between heat-generating components and heat sinks or other cooling devices (e.g., fans, heat spreaders or heat pipes). These tapes are pressure sensitive adhesives loaded with thermally conductive ceramic fillers. Pressure is needed to form a bond. Heat and pressure may be needed on some substrates to achieve an acceptable bond. The specialized acrylic chemistry of these tapes provide for good thermal stability of the base polymer. The thermally conductive tapes are on a silicone treated polyester release liner for ease of handling and die cutting. The tapes offer both good thermal conductivity and good electrical insulation properties. Tapes 9882, 9885, and 9890 provide best adhesion results when used with high surface energy substrates. If using low surface energy material, 3M Thermally Conductive Adhesive Transfer Tapes 8805, 8810, 8815, or 8820 could provide a higher adhesion bond and improved wet-out of the surface..
