    Abstract

    The swelling and decompression characteristics of a number of elastomeric materials were studied when subjected to high-pressure oxygen. The effects of varying the oxygen pressure, temperature, and moisture content of the gaseous oxygen were monitored. Some trials subjecting the elastomers to cyclic pressurization were also conducted. Volume swelling values from over 100% to less than 1% were noted for different elastomers. The results are interpreted in terms of the structural and mechanical properties of the specimens.
