Performance testing of elastomeric seal materials under low and high temperature conditions: Final report

Abstract

Management jointly sponsored a program to evaluate elastomeric O-ring seal materials for radioactive material shipping containers. Thk report presents the results of low-and high-. temperature tests conducted on 27 common elastomeric compounds. ACKNOWLEDGMENTS I thank the many Sandia National Laboratories Transportation Systems and Development Department members who have contributed to this work, including

9975 Shipping Package: Performance of Alternate Materials for Long-Term Storage Application

“…If Arrhenius behavior occurs across the full aging range, elevated-temperature CSR data are more likely to reasonably predict behavior at lower temperatures. However, several studies have shown non-Arrhenius behavior in certain elastomers, which can invalidate life prediction by CSR alone [9,10]. Non-Arrhenius behavior may occur due to oxidation at lower temperatures or other reasons.…”

Performance of metal and polymeric O-ring seals during beyond-design-basis thermal conditions

“…The test fixtures in previous work typically consisted of two flanges or two plates with two concentric O-ring grooves, one for the test seal and one for the secondary external seal, and a small cavity for helium tracer gas [6, 7]. A similar experimental configuration was used to examine the performance of elastomer seals at temperatures below 0 °C [8].…”
