An Arrhenius relationship is employed to develop a model for prediction of gas permeation in the polymeric materials. A permeation cell was designed to measure the gas permeation. The permeation of Helium was examined over a range of low to high temperature and pressure conditions. The results of the experiments were used to verify the accuracy of the prediction model.
The obtained model was successful in predicting gas permeation rate at two different pressures. The results showed that pressure’s effect is insignificant on models. The predicted results for different pressure were close, and both models can be used to obtain an approximation for gas permeation rate for the examined material where no experimental data exists.
