Gas permeation rate
Webuses gas permeation, but the principle is the same with liquids or chemicals. Permeation data are presented in two values: Breakthrough time and Rate. ... P – Poor; permeation rate of less than 9000 µg/cm2/min. 501 to 5000 drops NR – Not Recommended; permeation rate greater than 9000 µg/cm2/min. 5001 drops up WebMar 17, 2024 · The same trend, but with significantly lower permeation rates, was achieved when the samples were compression-molded at 240 °C. The permeation rate was reduced from 175 cm 3 /m 2 dbar for unfilled samples to 89 cm 3 /m 2 dbar for samples with 6.0 wt.-% filler content. This effect can be explained by the different degree of crystallization ...

WebBy Test Property. Gas Permeability Tester. Gas permeability is the ability of a barrier material to allow gases (O 2, N 2, CO 2 etc.) to permeate through it in a specific time. Gas permeability may vary with temperature, humidity, pressure and specimen thickness. Testing Method. WebOxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of …
