3M Thermally Conductive Acrylic Interface Pad 5589H is an acrylic elastomer based interface pad. It has high thermal conductivity, good electrical insulation properties and is ideally suited for applications that require non silicone properties.Because of its softness, Interface Pad 5589H can decrease the load to integrated circuit chips during compression, and have good tack to many surfaces. These properties lead to a high performance non silicone based thermal pad. Interface Pad 5590H is a higher thermal conductivity and somewhat firmer acrylic thermal pad, versus Interface Pad 5589H. Standard Lead Time: 52 Calendar Days
