What about permeation?
Permeation is the transport of a substance through a solid body (lat.: permeare = to perambulate, to go through, to pass).
The permeation rate describing the amount of permeating substance is determined by a permeation measurement. Leckage is permeation through leaks or defects, permeation however is also possible through defect free materials over molecular mechanism. Permeation through non porous material materials is described by solution-diffusion mechanism or crystal defect conduction.
Permeation as material property impacts about live time and efficiency of common items. In functional clothings high permeable membranes take care that we don't sweat excessively. A car fuel tank is designed to be as tight as possible to prevent fuel emission. Oxygen permeation makes beer to loose its aroma, but causes a part of the specific flavour of old red wine.
Mecadi supports customers of various industries to analyse such effects and to enlarge life time and efficiency of your products.
