Ultra-High Thermal Conductivity Silicone Thermal Pads

Ultra-high thermal conductivity silicone thermal pads are advanced thermal interface materials with a thermal conductivity of 8–15 W/m·K. Made with specially developed nano-material powder filling, they greatly increase thermal conduction paths while retaining excellent electrical insulation and temperature resistance. The pads conformably fill the gap between heat-generating components and heat sinks, delivering a reliable heat transfer path from the source to the cooling solution.

As a precision die-cutting manufacturer, Fangying converts these high-performance pads into finished parts that drop straight into your assembly — cut to your exact shape, from a single prototype to millions of pieces on the same tooling.

Key performance features

  • Ultra-high thermal conductivity — 8–15 W/m·K for high-power heat dissipation.
  • Self-adhesive — simplifies assembly without additional adhesive layers.
  • Low thermal resistance — efficient heat transfer across the interface.
  • Low oil bleed, high reliability — stable long-term performance under continuous operation.
  • High electrical insulation — safe for direct contact with electronic components.
  • Excellent temperature resistance — reliable over a wide operating range.

Frequently asked questions

What is the thermal conductivity of these pads?
8 – 15 W/m·K, confirmed on the material datasheet for each grade.

Can you die cut the pads into custom shapes?
Yes. We cut any 2D contour from your DXF, DWG, STEP or dimensioned PDF with rotary or flat-bed die cutting, from prototype to mass production.

Do the pads have self-adhesive properties?
Yes. The pads are self-adhesive, and we can also apply pressure-sensitive adhesive on request for automated assembly.

Are the materials compliant with environmental standards?
Yes. This series complies with RoHS, halogen-free and HF-controlled requirements.
