Outgassing rate of Reemay Spunbonded Polyester and DuPont Double Aluminized Mylar
This paper presents the outgassing rates of two commercially available multi-layer insulation (MLI) materials commonly used in cryogenic applications. Both Reemay Spunbonded Polyester and DuPont Double Aluminized Mylar (DAM) were studied for outgassing species and respective rates, and the total amount of outgassed material. Measurements were made using a Fixed Aperture Technique. A sample was pumped on through an aperture of known size with a turbomolecular pump. Pressure vs. time was plotted for both Reemay and DAM, as well as the baseline system, and data conveniently extrapolated to (approx)1,000 hrs. A quadrupole residual gas analyzer was used to measure the outgassing species. (ERA citation 18:033247)
