Need a lead on a non heat retentive/conductive material
(OP)
thread334-166140: Looking for a non heat conductive flexable material I am working on a project where it would be helpful to use a strong possibly moldable material that will not conduct/retain heat ie: will always remain cool to touch no matter what the surrounding ambient temperature is. Needs to withstand temperatures ranging from -10 degrees to 120 degrees farenhiet. I am thinking that my only choice is going to be a modified silicon polymer. What are your thoughts. Thanks

It's the white foam they use in the Mr. Clean sponges. It is intrinsically flame retardant. Also, you can dip it in liquid nitrogen then take it out and smash it with a hammer and it will not shatter but bounce back. It's a thermoset so it won't creep and it's cheap too.

Note further, that you've not specified thicknesses, amount of heat, etc., and any relatively thin layer of insulation will eventually pass some amount of heat outward, which could be sensed by touch. You wouldn't get burned, but then, 120°F is not a serous burn threat.
Assuming something with thermal conductivity comparable to styrofoam at 0.6 W/m-K, 120°F heat source on one side, and a hand at 75°F on the other, there would be about 1 watt transferred, which is not exactly "hot" but definitely not "cool."

The third is somewhat of combination of the two.
I have used the Hytec product as and additive to a high TiO2 white paint and as far as I know it worked well in situation similar to yours.

I'm not sure about Aerogelen, having trouble on their website. The Aerogel business was spun off from Aspen Technologies late last year.
