According to the supplier, 0.22 W/m/K at 23°C, see the link.

And obviously less at lower temperature.

James E Fesmire

Thank you. This is helpful information. I have some other suppliers' information with different data. I will keep looking for the lower temperature data.

Alan Kopelove

James, Paul Whitehouse at NASA GSFC has done some great work accurately measuring the thermal conductivity of ULTEM 1000 from 4K to 300K. I have sent you his data. Alan

David L Reens

Is this data published? I would also like to see it.

Thank you Alan. I am late to see this. David, I will find it and see.
