sound attenuator/absorber material with high thermal conductivity?
(OP)
I am sorry if this is coming to the wrong forum;
Anyone ever heard a sound attenuator/absorber material with high thermal conductivity?

That probably wasn't what you were looking for.
My goto guys for sound issues are Soundown. www.soundown.com
All of their stuff I've used uses a thin mass-loaded layer of solid-ish plastic between layers of plastic foam, but they may have other stuff that will work in your world.

IRstuff, I am afraid I am not permitted to provide intimate details since this is a research for a new project, I apologize. I can tell that the I need an attenuator/absorber which does not obstruct the cooling process… In other words, it must help dissipation of the heat produced by the component which causes unwanted noise.

Your post just reminded me what I forgot to mention initially:
We need it in foam form, if possible, max 1 millimeter thickness.
I think what we need is an thermally conductive open cell foam..
Can anyone recommend a source?

There are reticulated aluminum and carbon foams available for sale today...but bring your wallet. And they won't have the viscoelastic damping properties of elastomeric foams.

btrueblood, is it that hopeless?! ))) See what I just found (attached pic, it is from 3M, thermally conductive interface pad…), if provided at reasonable cost, this will do.. Do you have any idea who else has this at a reasonable cost? (Max continuous working temperature will be 100C)

By using a high loading, typically 60-80 weight% of filler you should be able to get a thermal conductivity of the composite over 1 W/m.K. That's not a guess, it's what's been reported in articles.

Very good info, thanks a lot,
I will check every info you mentioned,
In the mean time, as silicone is very expensive and the max continuous working temp in our application is around 100C, I am looking for alternative base materials, can you think of any candidates to fill?
