Gas Separation Membranes Testing, Gas Permeability Testing for Membranes, Gas Permeability Testing

Separation membranes selectively separate gases, and the separation coefficient of gases is a key performance index in measuring separation effect. In this paper, by testing the permeability of nitrogen and carbon dioxide to a certain membrane sample, the separation ability of the sample to nitrogen and carbon dioxide is evaluated. The test principle, the parameters, application of the pressure differential method testing equipment, and the test process are introduced. Reference for the analysis and test of the separation effect of the membrane is provided. Continue reading

Film materials, thickness, barrier properties, oxygen transmission rate, oxygen permeation, oxygen permeability, gas permeability tester, composite materials

Basically, increasing the thickness of film materials is one of the important measures to improve the barrier properties of packages. Meanwhile, the increase of materials thickness is bound to increase packaging costs. This article studied the influence of increasing the thickness of single layer membrane in composite materials on the barrier properties of packages, through test the oxygen permeation of film materials with different thickness.
