Silicone Thermal Pad 12.8 W/mK

This silicone thermal pad provides a 12.8 W/mK conductivity rating for transferring heat between components and heatsinks. It measures 120 by 20 by 2.0 mm and weighs 15 g. The grey pad is non-conductive, non-corrosive and non-curing. It suits laptops, GPUs, CPUs and LED coolers.

Practical Limits of Thermal Interface

The material operates continuously from minus 40 °C to plus 200 °C, with a long-term rating up to 400 °C. Breakdown voltage exceeds 9.8 kV at 1 mm thickness. Density is 3.1 ± 0.2 g/cc and hardness ranges from 30 to 55 on the Shore C scale. Performance depends on full surface contact and correct thickness matching.

Installation and Common Issues

Natural viscosity lets the pad adhere during assembly and allows repositioning or reuse. Cut the single sheet to the exact component footprint before placement. Common problems include trapping air bubbles, leaving gaps on uneven surfaces or selecting the wrong thickness for the stack height. Ensure mating surfaces are clean and flat.

Questions about this item

Should I choose the 120x20x2.0mm pad or a different thickness for my GPU?

The pad measures 120x20mm and is 2.0mm thick; select this size only if the gap between your GPU die and heatsink matches that height.

What does 12.8 W/mK mean for my laptop temperatures?

A conductivity of 12.8 W/mK moves heat from the die to the heatsink far faster than standard pads, lowering junction temperatures under load.

Is the pad electrically safe on exposed PCB components?

Yes — breakdown voltage exceeds 9.8KV at 1mm and the material is non-conductive, so it insulates nearby components while transferring heat.
