Basic Properties

Compared with other polymers, Nylon-MXD6 shows greater mechanical strength and elastic modulus. The properties of Nylon-MXD6 are contrasted with those of other polymers in Tables 1 and 2. Table 1 shows properties of injection-molded products and Table 2 shows Nylon-MXD6's properties as a biaxial-oriented drawn film.
