3M™ Thermally Conductive Acrylic Interface Pad 5590H
Thermally Conductive Acrylic Interface Pad | 5590H
3M™ Thermally Conductive Acrylic Interface Pad 5590H is a conformable, slightly tacky acrylic elastomer thermal interface material containing a conductive ceramic filler. It is designed to provide a preferential heat transfer path between heat-generating components and cooling devices such as aluminum plates and heat sinks.
Key Features
- Thermal conductivity of approximately 2.08 W/m-K for efficient heat transfer.
- Conformable acrylic elastomer helps fill gaps and accommodate non-flat surfaces.
- Good electrical insulation properties for electronic thermal management.
- UL94 V-0 listed for flame-retardant performance.
- Soft, compliant construction allows pressure relaxation and helps reduce high pressure zones on components.
- Thin acrylic layer supports easy handling, pre-assembly and die-cutting.
