PARKER CHOMERICS LOW NASA OUTGASSING PRODUCTS

2023-12-28

■Many specifications require that nonmetallic components be virtually free of volatile residues which might outgas in the hard vacuum environment of space. The standard test method for determining outgassing behavior is ASTM E595, which provides for measurement of total mass loss (TML) and collected volatile condensable materials (CVCM) in a vacuum environment.
■Data for a number of Parker Chomerics conductive elastomers, based on ASTM E595 testing done by NASA Goddard Spaceflight Center, is presented below.
■The normal specification limits or guide-lines on outgassing for NASA applications are 1% TML max., and 0.1% CVCM max.
