As a collectively owned research and testing institution, Baijian.com can conduct breathability testing and issue breathability testing reports. The testing cycle is short, and a breathability test report can be issued within 7-15 days. Low testing cost, scientific and reliable data, fair and rigorous, integrating testing, inspection, analysis, testing, technical consulting and other services, can be used for testing breathability performance. Having the national high-tech enterprise certificate and CMA testing qualification certificate, with complete testing instruments, the testing report can be issued within 7-15 days Detection scope: Plastic film, composite film, high barrier material, sheet, metal foil, etc Testing items include gas permeability, solubility coefficient, diffusion coefficient, permeability coefficient, etc Testing standards BS 6092-11-1981 Sampling and testing methods for industrial sodium silicate and potassium silicate.
