This test method provides for the determination of 1 gas transmission rate GTR2 permeance, and, in the case of homogeneous materials, 3 permeability. VAC-V3 is designed for the measurement of gas permeability rate, solubility coefficient, diffusion coefficient and permeability coefficient at various temperature of plastic films, laminated films, high barrier material, sheets, foils, etc.

Even in essentially homogeneous structures, variations in morphology as indicated, for example, by density and thermal history may influence permeability. Labthink has more than 50 international distributors and more than 30 international service providers.
