Description:
During the first phase of tempering of polyamide-6, there are temporary changes which are apparently related to the lamella structure of the material. Test specimens at high temperature show that the mechanical properties of polyamide-6 are changed permanently, and mostly at 80 C. From the results of density tests and X-ray analysis, it follows that these changes depend on environmental influences and differ in gaseous and liquid media. The results of the test specimens of the mechanical properties as a function of temperature and the medium give information about the practical applications of polyamide-6.
