Abstract
The rheological characterization of polyethylene melts by using glass capillaries was investigated. Different polyethylene melts were characterized in a capillary rheometer by using glass capillaries and the results were compared with those obtained by using standard dies of tungsten-carbide, in addition to some homemade from aluminum. The data from glass capillaries showed an excellent agreement in all the cases with the data obtained with metal capillaries, and differences in the flow curves due to the influence of capillary materials were not detected. These results evidence the good performance and reliability of glass capillaries to perform the rheological characterization of this sort of polymer melt.
