Creep/aging behavior study of compressed fluorinated silicone rubber O ring

Through modification and extension of the creep dynamic model, this article introduced a substance macro-change dynamic model produced by active particulate under environment effect, which contains the primary creep dynamic model, and is applicable in describing complex physic chemical change process. The model is well applied in analyzing the creep/aging behavior of compressed fluorinated silicone rubber O ring in a wide temperature range from room temperature to 200℃, in addition, it exhibited a nice stability in room temperature with long term extrapolated validation. Two new phenomenon were discovered in the process of describing the aging behavior of compressed fluorinated silicone rubber O ring: the volatilization effect affects the creep/aging behavior of compressed fluorinated silicone rubber; there is a characteristic temperature (84.049℃) for the compressed fluorinated silicone rubber O ring, the creep/aging will be enhanced either the temperature is higher or lower than this characteristic temperature.
