Abstract
To optimise heat transfer in industrial processing of plastics like injection moulding or extrusion it is necessary to
determine thermal conductivity under different pressures and temperatures.
As an additional tool for capillary rheometer testing equipment a transient line-source sensor according ASTM
D5930 for heat transfer measurement was developed. The test device is introduced. Measurement results of different
polymer materials are presented. A strong influence on pressure and temperature can be observed. The results are
comparable to results obtained by other devices.
