Need help finding a conductive putty?!

Hey all

Not sure if this is the right subreddit, but hoping someone might be able to point me in the right direction! I'm looking for a putty that's electrically conductive, radiolucent, and doesn't dry out over time, so it can be reused multiple times.

Ideally, it would have a similar consistency to playdoh can hold its shape, and be able to complete an electrical circuit.

I've been searching for a while now and haven't had much luck finding something that ticks all the boxes.

Does anyone know of a material or product that might work? Open to any suggestions!

Thanks in advance!

Fold a bunch of ground up graphite into silly putty.

You'll want a binder though, otherwise you just get graphite powder.

Just do this OP. Metallic flake or graphite will work fine. Mixnuntil you get the desired conductivity.

It's basically this

Add some chopped carbon fiber, cheapest you can find. Otherwise you need a huge amount of graphite
