Description
3M™ Thermally Conductive Acrylic Interface Pad 5590H is a moderately conformable and medium-soft pad with high thermal conductivity of 2.8 W/m-K (3M test method). This pad consists of a slightly tacky acrylic elastomeric sheet filled with thermally conductive ceramic particles. It is designed to transfer heat from heat generating components to heat sinks and cooling devices, improving device reliability and extending the component’s life.
3M™ Thermally Conductive Acrylic Interface Pad 5590H has a medium-soft pad that conforms to uneven substrates, providing excellent wettability to fill gaps for improved thermal performance. The thin, firm, low-tack layer provides easy handling for pre-assembly and die-cutting. This pad provides robust thermal management for applications in a variety of market segments, such as consumer electronics, automotive, LED lighting, medical devices, communication infrastructure, and aerospace & defense.
Our family of 3M™ Thermally Conductive Acrylic Interface Pads provide low-outgassing and high-performance solutions compared to silicone. These acrylic pads have no siloxane VOC or oil bleeding, which are associated with silicone products and can often cause device failure. They are lightweight, making them ideal for applications with finer spacing requirements and a small footprint. 3M™ Thermally Conductive Acrylic Interface Pads have good electrical insulation properties to protect against electrical interference and device breakdown.
