| Through high-temperature accelerated aging test and damp heat test, the failure rule of F-108fluorine rubber o-ring under different environments was analyzed and the storage life of F-108fluorine rubber o-ring at25℃was evaluated. The results indicated that hygrothermal aging rate of fluorine rubber at70℃, 85% RH and70℃, 95% RH is7.47times and 8.65times of hot air aging rate respectively; early in the hot air aging, permanent deformation of rubber compression caused by non-chemical factors is much larger than chemical factors; the storage life of fluorine rubber o-ring is about10years, but the life will be greatly shortened under the hygrothermal environment. |
