Abstract


A study was conducted to measure and evaluate rheological properties of radiation-crosslinked polyamide 12 (PA12) with respect to the material's vacuum thermoformability. Rheological measurements in shear and uniaxial elongation were conducted to characterize the effects of temperature and crosslinking. Gel fraction analysis was carried out to investigate the degree of crosslinking after irradiation. Electron-beam irradiation of extruded sheets was accomplished with a 5-MeV electron accelerator. Irradiation doses were set to 15 kGy and 66 kGy for films with 4 and 12 wt% of crosslinking masterbatch. The e-beam treatment was performed in two repeated steps for a radiation dose of 66 kGy, each having a dose of 33 kGy, in order to keep thermal load low. The degree of crosslinking achieved by irradiation was determined by gel fraction analysis.
