摘要：

This paper presents the influence of processing temperature on the mechanical-physical properties of thermoplastic polyurethanes (TPU) used at injection moulding of performance sport products. The test-pieces were moulded at the following real injection temperatures: 200 degrees C, 210 degrees C, 220 degrees C, 230 degrees C and 240 degrees C. It was determined that the in-mould pressure decreased with increasing of the processing temperature. Also the following thermal analysis were performed: Thermogravimetry (TG), Differential Scanning Calorimetry (DSC) and Dynamic-Mechanical Analysis (DMA). It was established that the processing temperature has a significant influence on the thermal stability and on the glass transition temperature of polymer while the flow temperature is slightly influenced by the processing temperature.
