    Material Selection, Insulator, Cryo Temp

    Wool? Nice. Now that's thinking outside the box. I like people like you. I'm going to be putting the insulator in -370 F conditions so I'm sticking with PTFE for now. There is a seal area with critical dimensions so I'm using PCTFE (NeoFlon) for that as PCTFE is good to -400F while PTFE is...

    Material Selection, Insulator, Cryo Temp

    Thanks. Someone on the engineering forum said the same thing. What about polycarbonates though? They can have lower thermal conductivities but I'm not sure of their performance at cryo temps. Thoughts?

    Material Selection, Insulator, Cryo Temp

    Hi, I've got an applications where I need an insulating washer/disk in order to insulate stainless from stainless at 50 degrees Kelvin. I need help in selecting a material to do the job. I.e. low thermal conductivity, durable enough at 50 K to take a compressive static load of approx 40...
