3M Thermally Conductive Acrylic Interface Pad 5590H vs Bergquist (Henkel) Bergquist Gap Pad 2500S20: Comparison
What is the difference between 3M Thermally Conductive Acrylic Interface and Bergquist (Henkel) Bergquist Gap Pad?
Expect a near tie. The closest thing to a difference is thermal conductivity, 3M Thermally Conductive Acrylic Interface 2.08 W/mK against Bergquist (Henkel) Bergquist Gap Pad 2.4 W/mK. There is a split on reapplication interval as well, No reapplication needed; self-adhesive one-time application on the 3M Thermally Conductive Acrylic Interface versus No reapplication needed; reusable reinforced silicone sheet on the Bergquist (Henkel) Bergquist Gap Pad. They differ on conductivity source too, https://multimedia.3m.com/mws/media/920112O/3m-thermally-conductive-acrylic-interface-pad-5590h-technical-data-sheet.pdf on the 3M Thermally Conductive Acrylic Interface versus https://next.henkel-adhesives.com/us/en/products/thermal-management-materials/central-pdp.html/bergquist-gap-pad-tgp-2400/112643IB.html on the Bergquist (Henkel) Bergquist Gap Pad.
3M Thermally Conductive Acrylic Interface vs Bergquist (Henkel) Bergquist Gap Pad: which one fits your build
The 3M Thermally Conductive Acrylic Interface suits silicone-sensitive assemblies near optics, displays or connectors and power electronics and battery gap filling, though it is not built for high-end GPU memory or VRM cooling. It is not the one for builds where silicone pads are acceptable and higher conductivity is wanted. The Bergquist (Henkel) Bergquist Gap Pad is the one to take for general electronics gap filling and mainstream CPU/GPU, though it is the wrong buy for high-power dies needing >5 W/mK. Our rating of the 3M Thermally Conductive Acrylic Interface (6.6/10): an industrial acrylic interface pad from an established materials manufacturer, aimed at OEM and repair use rather than enthusiast builds. Our rating of the Bergquist (Henkel) Bergquist Gap Pad (6/10): A lower-conductivity industrial gap pad, suited to less demanding OEM cooling needs.
Frequently asked questions
Do the 3M Thermally Conductive Acrylic Interface and Bergquist (Henkel) Bergquist Gap Pad differ on compound type?
Yes. Compound Type reads Acrylic Pad on the 3M Thermally Conductive Acrylic Interface versus Silicone-Based Pad on the Bergquist (Henkel) Bergquist Gap Pad.
Is the Electrical Conductivity the same on the 3M Thermally Conductive Acrylic Interface and Bergquist (Henkel) Bergquist Gap Pad?
It is. Both are listed at Insulating, so it is not a reason to pick one over the other.
