Breathable films arkema has developed a technology for making monolithic breathable membranes breathability can be described as the moisture vapour transmission rate (mvtr) and it represents the amount of water vapour that passes through a film or a structure over a certain period of time. The pebax®2533 membranes showed high organic gas permeabilities plasticization effects on the membrane were pronounced with propane and propylene at elevated pressure (100 psig) activation energies of permeation (ep) were determined. Thesis archives the links below provide theses abstracts for the full text, please contact chris macosko for access, or search the electronic theses database proquest. Pebax 7233 is performing perfectly due to its high flex modulous, energy return, and ability to withstand cyclical fatigue (does not seem to take a set), low crack propagation, etc the only problem it's cost prohibitive.
