Abstract

Results are presented relating to the outgassed products from three common insulating polymers under vacuum at elevated temperatures up to 400 degrees C. Nylon-6, polymethylmethacrylate and polytetrafluoroethylene (PTFE) have been studied. PTFE is the most stable, while nylon-6 outgasses large quantities of water vapor. Preliminary results of a longer term investigation of the insulating characteristics of vacuum polluted by outgassing from polymeric materials are reported. The work has relevance to the development of high-voltage power systems in space.<>
