3M™ Thermally Conductive Acrylic Interface Pad 5590H
Thermal Pad Roll | 1.0mm Thickness | 240mm Width × 20m Length
3M™ Thermally Conductive Acrylic Interface Pad 5590H is a soft, conformable thermally conductive acrylic elastomer pad designed to provide a preferential heat transfer path between heat-generating components and cooling devices such as aluminum plates and heat sinks. The material uses a thermally conductive ceramic filler in an acrylic elastomer construction and is designed to provide good thermal transfer, electrical insulation, softness, conformability and pressure relaxation.

Product Highlights
High Thermal Conductivity
3M 5590H provides a highly thermally conductive interface for transferring heat from electronic components to heat sinks and cooling plates.
Soft & Conformable
The acrylic elastomer construction provides good softness and conformability for uneven and non-flat mating surfaces.
Electrical Insulation
Good dielectric performance helps provide electrical separation while maintaining thermal transfer across the interface.
UL94 V-0
UL94 V-0 flame-retardant performance makes the material suitable for demanding electronic and industrial thermal applications.
Non-Silicone Construction
The acrylic elastomer construction does not contain intentionally added silicone, helping avoid siloxane VOC and oil-bleeding concerns associated with silicone materials.
Compressive Stress Relaxation
The soft and compliant material allows pressure relaxation and can help reduce high pressure zones on sensitive components.

Product Uses
3M™ Thermally Conductive Acrylic Interface Pad 5590H is designed to provide a preferential heat transfer path from heat-generating components to cooling devices such as aluminum plates and heat sinks.
The soft, conformable acrylic elastomer construction helps the material adapt to non-flat surfaces and fill interface gaps. This can improve contact between the heat-generating component and cooling structure.
The 5590H material provides good electrical insulation, surface tack and compressive stress relaxation while maintaining thermal transfer performance. Its compliant construction can help reduce high pressure zones on sensitive components.
Typical applications include battery cooling, power electronics and HMI displays. The material can also be considered for electronic modules, heat sink interfaces and selected automotive thermal management applications.
The 240 mm × 20 m roll format is suitable for industrial converting, slitting and production applications where a continuous thermal interface material is required.
The material also incorporates a thin acrylic layer that supports handling during pre-assembly and die-cutting, making it suitable for custom converted thermal interface components.
Custom Converting & Die-Cutting
Custom Die-Cutting
3M™ 5590H thermal pad can be die-cut into custom shapes, sizes, holes and cut-outs according to application requirements and customer drawings.
Sheet & Slitting
The 240mm × 20m roll can be converted into custom widths and sheet formats for easier handling, assembly and production requirements.
Application-Specific Shapes
Custom thermal interface components can be produced with application-specific geometries, slots, openings and profiles based on customer requirements.
