Over on mouser, under TIM products, they have a couple of products listed as Panasonic Thermal Interface Products Graphite-PAD. It comes in thicknesses from 0.5mm to 3mm in 0.5mm increments. The description from the Panasonic datasheet says:

'Graphite-PAD is a thermal interface material (TIM) that compatibly obtained excellent thermal conductivity in thickness direction (Z-axis direction) and high flexibility (deformable with a low load). The properties are greater than that of existing TIMs. The product is created by filling PGS Graphite Sheet into silicon resin.'

The thermal conductivity reported is 13 W/m・K . The Volume resistivity (Ω·cm) is 4×10^5. So it's electrically conductive?

In general, graphite is electrically conductive, even the one used in graphite thermal pads.

The conductivity is usually at least within same grain of the material, and this looks quite similar to pad used in Radeon VII (sort of mush of glue and graphite).

Not exactly a product for PC enthusiasts, but perfect for products like phones, cameras, where the chip is glued with such pad to the cover.

I was hoping it might be a better thermal pad than Fujipoly Ultra Extreme pads since the Panasonic pad claims high flexibility and has pretty good thermal conductivity. Too bad.
