Isn't that dependent on what PI is used? There are a whole bunch of
polyimide films with various data. And what outgassing do you want to
know about? Vapour?  Nitrogen? Helium? Oxygen? Carbon dioxide? The
permeability of nitrogen is about 1,000 mL/m2x24hsxMPa while it's 65,000
for Helium. And the outgassing is dependent on the ambient pressure.
Will be interesting to see more answers. We had a similar question as
you once, and we never got very good information. So we performed own,
taylored, outgassing tests.

Subject: [TN] Outgassing requirements and Polyimide material


Would anyone have any technical data sheets for Isola Polyimide material
that contains information on whether it meets the outgassing
requirements of Nasa Publication 1124, specifically TML of 1.0% and CVCM
of 0.10% Max.

 

All my contacts including technical team cannot seem to locate such
information.
