Quarterly report for December 1, 1961 to March 1, 1962 on elastomeric seals and materials at cryogenic temperatures

Abstract

The study of elastomeric seals at cryogenic temperatures has moved through the stages of initial development and functional test¬ ing!! 1 1 into a more analytical and fundamental program.At present the program consists of four experiments, one of which involves the direct measure of leak rate through a seal.The other experiments are designed to study the low temperature behavior of elastomeric polymers in terms of thermal expansion, resilience, force-tempera¬ ture relationships, and differential thermal analysis .
