3M™ Thermally Conductive Acrylic Interface Pad 5571
Thermal Pad Roll 300mm × 20m | 1.5mm Thickness
3M™ Thermally Conductive Acrylic Interface Pad 5571 is a conformable thermal interface material designed to provide a preferential heat transfer path from heat-generating components to cooling devices such as aluminum plates and heat sinks. It consists of a slightly tacky acrylic elastomer with a thermally conductive ceramic filler.
Key Features
- High thermal conductivity of approximately 2.1 W/m-K for efficient heat transfer.
- UL94 V-0 listed for demanding electronic and industrial applications.
- Good electrical insulation properties help provide electrical separation between components and cooling structures.
- Conformable acrylic elastomer fills gaps and helps improve contact between uneven surfaces.
- Slightly tacky surface helps support thermal interface installation and wetting.
- Soft and compliant construction allows pressure relaxation and helps reduce high-pressure zones on components.
- Does not contain intentionally added silicone, helping avoid siloxane VOC and oil bleeding associated with silicone-based materials.
- Large 300mm × 20m roll format is suitable for industrial converting, die cutting and high-volume production requirements.

Product Uses
3M™ Thermally Conductive Acrylic Interface Pad 5571 is designed to provide a preferential heat transfer path between heat-generating electronic components and cooling devices such as aluminum plates and heat sinks.
The 1.5 mm thick construction provides a soft and conformable thermal interface that can help fill surface irregularities and air gaps between mating surfaces. The acrylic elastomer contains a thermally conductive ceramic filler to provide efficient heat transfer.
The material also provides good electrical insulation properties, making it suitable for applications where thermal conduction and electrical separation are both required.
Typical applications include battery cooling, power electronics and HMI displays. The material can also be considered for automotive electronics, LED lighting systems, power supplies, inverters and other electronic thermal management applications.
The 300 mm × 20 m roll format is suitable for industrial converting, die cutting, laminating and high-volume manufacturing applications.
For optimal thermal performance, the mating surfaces should be clean and dry and the pad should be compressed appropriately to achieve good surface contact. Avoid overstretching or sharply folding the material during installation.
