Abstract
Heat transfer is important to optimise polymer processing.
Since recent years model processing is getting more and
more important to successfully simulate divers processes.
Commercial software requires a range of heat transfer
parameters. A triple bore capillary rheometer has been
designed to provide one single bore for measurements of
the thermal conductivity while the second and the third
bore is still available for routine viscosity tests, ideally on
the same material. A conductivity probe is placed in the
dedicated bore. A heating wire and a thermocouple are
placed into the probe. A defined amount of heat is
transported to the heating wire. The increase of
temperature is measured by the thermocouple. Results will
be presented for different polymer melts.
