High Temp Insulation for test section
(OP)
Hello everyone,
I'm in a desperate need for a polymer which I could use on my test section to electrically insulate parts of it. My problem is that we estimate that the temperature can reach up to 500C and that is why I have problems finding some.
I would like to ask as well if anyone could help me in finding a high temperature (up to 300 - 350C) thread sealing material - PTFE tape can go only up to ~250C so I need to find an alternative. Thanks to some of you from another forum I think that I should be looking for something like Grafoil tape - but any more information or alternatives would be greatly appreciated.
Thank you very much for your help in advance.
Kind Wishes,
George
ps
European or UK based companies would be ideal but I will be happy with any information.

You mentioned electrical isolation, remember that graphite (main component of Grafoil) can be conductive.

1)electrically insulating polymer polymer up to ~500C
2)thread sealant up to around 300C (doesn't have to electrically insulate) - so grafoil tape should be suitable but I can only find US suppliers - and maybe there are some alternatives for it?
Hope that clears things a little bit
Cheers,
George

For the second point I would direct you to C.S. Hyde who sell just about every kind of polymer tape, sheet and foil there is. That includes high temperature polymers.

This site lists them all with properties too

Also, you can search for free by property at

You can get epoxy that retains mechanics including modulus to over 300C from www.hybridplastics.com (disclosure, I work there).

Solvay recently aquired PEEK resins from Gharda. Gharda made some strong claims re development of new grades with exceptional properties even for PEEK. They also had what they called Super Sulphones. I can find their data if you have trouble getting it from Solvay. We lost the Gharda agency at that time as Solvay already had an established competent effective agent here.
