3M™ Thermally Conductive Acrylic Interface Pad 5571
Log Roll | 1.5mm Thickness | 300mm Width × 20m Length
3M™ Thermally Conductive Acrylic Interface Pad 5571 is a conformable, slightly tacky thermally conductive acrylic elastomer pad with a conductive ceramic filler. It is designed to provide a preferential heat transfer path from heat-generating components to cooling devices such as aluminum plates and heat sinks.
Key Features
- Thermal conductivity of approximately 2.1 W/m-K for effective heat transfer.
- Conformable construction helps fill gaps and accommodate non-flat surfaces.
- Good electrical insulation properties for electronic thermal management applications.
- UL94 V-0 listed for flame-retardant performance.
- Soft, compliant acrylic elastomer allows pressure relaxation and reduces high pressure zones on components.
- 300mm × 20m log roll format is suitable for industrial converting, slitting and die-cutting.
Product Highlights
2.1 W/m-K Thermal Conductivity
Provides an efficient thermal transfer path between heat-generating components and cooling structures.
Conformable Material
The soft acrylic elastomer conforms to uneven and non-flat surfaces while helping fill interface gaps.
Electrical Insulation
Good electrical insulation properties help provide separation between electronic components and cooling structures.
UL94 V-0 Listed
Flame-retardant performance supports demanding electronic and industrial thermal management applications.
Non-Silicone Construction
The product does not contain intentionally added silicone, helping avoid concerns associated with siloxane VOC and oil bleeding.
Easy Die-Cutting
The acrylic pad construction incorporates a thin layer that supports handling during pre-assembly and die-cutting.

Product Uses
3M™ Thermally Conductive Acrylic Interface Pad 5571 is designed to provide a preferential heat transfer path from heat-generating components to cooling devices such as aluminum plates and heat sinks.
The 1.5mm thick acrylic elastomer construction provides a soft and conformable thermal interface that can help fill gaps between mating surfaces and accommodate non-flat substrates.
The slightly tacky surface helps with pre-assembly, while the conformable construction provides good contact across the thermal interface. The material also provides good electrical insulation properties.
Typical applications include battery cooling, power electronics and HMI displays. The material can also be converted into custom thermal interface components for specific electronic assemblies.
The 300mm × 20m log roll format is suitable for industrial converting, slitting, sheet conversion and high-volume production requirements.
Custom Converting & Die-Cutting
Custom Die-Cutting
3M™ 5571 thermal pad can be die-cut into custom shapes, sizes, holes and cut-outs according to application requirements.
Sheet & Slitting
The 300mm × 20m log roll can be converted into custom widths and sheet formats for production and assembly requirements.
Application-Specific Shapes
Custom thermal interface components can be produced with specific geometries, openings, slots and profiles based on customer requirements.
