best thin thermally nonconductive material
(OP)
What is the best thermally nonconductive material I can get that is thin?
Need to put it between the intake side of a IC and a airbox I am making
My scenario is that the IC is going to be around 200*F and pressed up against a aluminum airbox.
I wish to use a very thin nonconductive material with properties like asbestos or ceramic matting.
I am just not sure what material would be the best to stop energy from transferring through one aluminum surface to another in direct contact.
Here is a link to some materials I am considering. Anybody care to elaborate on which materials have the most desired properties and that can be found in a thin material, around 1/8 to ΒΌ inch?

RE: best thin thermally nonconductive material
In the meantime consider whether low density (0.05 g/cm3) cork at 100oC could be a good insulator with a thermal conductivity of 0.04 W/(m.K).

Any comments on perhaps using a silicone based material?
Such as the material that is used in making turbo hose couplers, but in a flat sheet.
Also does anyone have any good links or references I could look up the thermal transfer properties of different materials?
Sorry about the link I should have checked it http://thermal_insulation_material.manufacturers.alibab...
Thank you for any input
RE: best thin thermally nonconductive material
Otherwise you must make another choice: if you want a really good insulating material, then the mechanical properties won't be good: the best insulators are in fabric, textile or even powder form, and that's because that way they entrap air (like cork BTW).
If you want a solid material, then your thermal conductivity will be higher: simply choose the lightest material you can live with (PTFE for example weighs about two times as most elastomers, so it wouldn't be a good choice). If you can accept a kind of foam (more or less dense is up to you, and of course with closed cells), then that will be the good one.

RE: best thin thermally nonconductive material
I can't quite picture your application, but it helps to understand all the thermal paths. If the 200F surface has good alternative thermal paths, you may not need a high-tech insulator. On the other hand, if all the other paths are poor, radiative heat transfer could bypass your attempts to isolate it.
Good luck,
