In search of SOFT insulation.

In search of SOFT insulation.

In search of SOFT insulation.

(OP)
Hello,

I have been searching..in vain, for thermal insulation.

While there is a huge number of insulating materials available. (a surprising amount) I am having some difficulty finding what I am looking for.

I am looking for insulation that is soft and conforming and will operate at 500F or more preferably 1000F.  My dream material would be like inch wide cotton bandage gauze, the white stuff.  This way I can wrap my heater device conforming to its shape and avoiding wire connections, etc.  It could be fiberglass even, but I can only find thick stuff - inches thick..  I would rather something more like 1/8 or 1/16 or maybe 1/4 inch.

Any ideas or a name I can search out?

Thanks.

RE: In search of SOFT insulation.

You can use Fiberfrax.  I've wrapped high temp tubular type furnaces with this stuff all the time.  Used at well over 1000F.  The blankets are tearable and compressable to fill gaps.  Its almost tears like cotton, but tougher.  Keep in mind that if you thin it out, this can reduce its insulating efficiency.

Thanks for the info.  Some of it looks pretty good.

If it has to flex only during manufacturing and be fix later you may use magnesium oxide -- wrap the heater with
metallic Mg band and oxidize it with superheated H2O

-- used for making heaters.

Interesting!  No need for post assembly flexibility. I will look into that.  Non-conductive I hope.

Keith:
Yes, it is used e.g. in the immersion heaters (the one used to reheat a cup of coffee)
Suggest look up the patent -- but it may be too old
for WEB search...
