For films, in several series of experiments concerning various thicknesses of various polymers, permeability coefficients have been calculated for a reference thickness of 40 /xm. Units differ for the various gases but are comparable for the different polymers tested with the same gas. The following data (without units) are only given to provide a general idea and cannot be used for designing any parts or goods. 

At strains >10%, when the polymer structure has begun to collapse, gas loss, by diffusion through the cell faces of closed cell foams, may contribute to the creep. The effect of this on the creep of LDPE and EVA foams was determined (266). The foam diffusivity for air was predicted from the polymer permeability P and the foam density p using ... 

The figure also shows that the highly permeable zeolite only has a large effect on polymer permeability when the percolation threshold is reached. That is, useful...
