G2/131 Gas Permeability Tester for Films and Sheeting is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheets, and aluminum foils at different temperatures. The system is equipped with three diffusion cells, which could test specimens simultaneously with individual test results. The testing process conforms to GB, ISO, ASTM and other international standards.
Gas Permeability Tester for Films and Sheeting is applicable to the determination of gas permeability of:
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others
Including engineering plastics, rubber and building materials, e.g. PP, PVC, and PVDC
