Gas Barrier Technologies, include Nylon-MXD6
Nylon-MXD6 shows excellent gas barrier performance compared with Nylon-6 or PET. The oxygen permeation rate of Nylon-MXD6 and other polymers are shown in Table 1 and Fig. 1. The gas barrier performance of Nylon-MXD6 is much less moisture sensitive than EVOH. Because the gas barrier performance of EVOH varies dramatically with relative humidity, Nylon-MXD6 shows better gas barrier performance in a humid atmosphere.
