Electrically non-conductive but thermally highly conductive material
Electrically non-conductive but thermally highly conductive material
(OP)
I am looking for a material which is electrically non-conductive but thermally highly conductive.
Need the material in sheet form, like a gasket, any thickness between 1/4 inch and 1/2 inch would be perfect,
Doesnt have to be flexible, bendable etc, can be either soft or very solid,
Wont bear any physical pressure,
Operating temp: 180 F,
Needless to say, must be commercially available ))
Guys, thanks a lot in advance,
Jakelian

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

As a chem eng/metallurgist the first part of any answer I give starts with "It Depends"

IRStuff:
Only requirements I can think of at this stage (and with my knowledge) are, max temperature; 180F, thickness; upto 1/2 inches. Values about electrical or thermal insulation? I dont feel like I have that info or the luxury to ask those at this moment. I mean, if I find something with 50 WmK, it is better than nothing. Or 40 WmK but cheaper, it will work better.. I just have to see the cost.. Then if affordable for the product, think of it as $s per W/mK, then test it on its place to see what difference it makes..
I am checking the alumina pads, I think 1550C temp is kind of overkill for my 180F application, and for 0.13 thermal conductivity, it may just not worth it, I am cheking...
Itdepends:
Thanks but thermal grease wont stay there for long , I need something that can hold itself better, for example, a soft blanket would stand there.. (I forgot to say that the application stands vertical, Itdepends, sorry, my bad).
Gruntguru:
That WORKS, (if it is affordable), I am on it! I am giving you a star for the best answer, thank you very much :)
Guys, I appriciate your attention))
RE: Electrically non-conductive but thermally highly conductive material
Alumina ceramic is somewhere between 12 and 30 W/m K or so, and is pretty cheap.
Silicon carbide can be 50-100 W/m K, but is a lot more costly.
RE: Electrically non-conductive but thermally highly conductive material
Thank you for correcting me, yes, now I found alumina with 29W/mK, far superior to those pads (star).
Can you think of any US manufacturer who provides it in sheet form?
Oh pls dont bother, I am cheking with ThomasReg,
Thanks a lot)

Thanks, I checked your link, empty page
comes up. Then I went their home page and searched. I found several options, one of them is:http://www.goodfellow.com/catalogue/GFCat4I.php?ew...
So,
25x25mm, with 10mm thickness, price: 235 Sterling?? (So, what is the size of the sheet? 25mm x ?)?
btrueblood, the product can not afford those,
zapped again, yes, I need it at least 1/4 inches...
For actual production, I will need the material for 500mm x 2000mm, in other words, 19.6" x 78.7". So, it must be really affordable. Any more ideas?
Thanks again,
J

Thank you very much for your attention,
Good thinking, but, about aluminium and copper: Absolutely no metals around.. So, cant use them; they cause other problems..
Thanks anyway for the thought anyway.
ceramic block, yes, i am searching that one...)) thanks..

Thank you very much for your attention,
I solved the problem by using some polyester foil, it was easier than I thought,
Thanks a lot anyway for your attention,
