rubber, however it appears that the rubber has increased in resistance.
The pads either wear or "dry out" or something, never worked out which.
I talked a mate of mine through repairing some vintage synthesizers
which use conductive pads for the control panel (Sequential Six-Trak,
Alesis drum machine and sequencer) by taking the panel apart and
painting a blob of silver-loaded paint for repairing heated rear windows
in cars. The bottle was a couple of pounds from Halfords, and probably
cheaper in your local independant motor factors. A tiny bottle lasts
for ages because you only need a little spot.
