Yes, both the Arrhenius and Peck models are utilized for predicting the lifetime of polymers under various environmental conditions.
Arrhenius Model: The Arrhenius equation describes the temperature dependence of reaction rates, which is applicable to the degradation processes in polymers. By conducting accelerated aging tests at elevated temperatures, the Arrhenius model allows for the extrapolation of polymer lifetime at normal service temperatures. This method assumes that the degradation mechanism remains consistent across the temperature range tested.
Peck Model: The Peck model extends the Arrhenius equation by incorporating the effects of both temperature and humidity on the degradation rate. This is particularly useful for polymers susceptible to moisture-induced degradation, as it provides a more comprehensive understanding of environmental influences on polymer longevity.
It's important to note that while these models are valuable tools, their accuracy depends on the validity of their underlying assumptions. For instance, the Arrhenius model presumes a single dominant degradation mechanism and a constant activation energy over the temperature range studied. Deviations from these assumptions can lead to inaccuracies in lifetime predictions.
