View the original post on their site here: https://www.uccomponents.com/vacuum-permeation-in-o-ring-polymers/ Permeation, or the permeability coefficient, of a polymer refers to the volumetric flow of gasses, under controlled conditions, through the material’s surface. Permeability does not equal leakage! Leakage refers to gasses that flow around the seal. Permeation is a
