| Abstract: | Leakage of perfluoroether rubber O seals under cryogenic condition was analysed theoretically. Parameters of the second vulcanizing process were adjusted and the cryogenic sealing tests were conducted for the purpose of compression performance improvement. The results show that the cryogenic sealing properties of the perfluoroether rubber seals were improved effectively without changing of the physical and mechnical properties. |
