Webdata on hydrogen permeation are available and no mechanistically-based models to quantitatively predict permeation behavior have been developed. However, several qualitative trends in gaseous permeation have been identified and simple calculations have been performed to identify leakage rates for polymers of varying crystallinity. WebA permeation tube is a sealed permeable membrane containing a chemical component, typically in liquid form, that permeates through the walls of the membrane at a constant rate (see Figure 1). This constant rate is referred to as the permeation rate. The permeation tube is maintained at a constant temperature inside WebThe meaning of PERMEATE is to diffuse through or penetrate something.
