3M™ Thermally Conductive Acrylic Interface Pad 5590H is a high-performance thermal interface material designed for efficient heat transfer in electronic devices. With 3.0 W/m-K thermal conductivity, this medium-soft, conformable acrylic elastomer ensures effective heat dissipation while providing electrical insulation and UL 94 V-0 flame retardancy. Its non-silicone composition prevents siloxane outgassing, making it ideal for consumer electronics, automotive systems, LED lighting, medical devices, and telecom infrastructure. Available in multiple thicknesses, 3M 5590H enhances device reliability by optimizing thermal management in critical applications.
