摘要：This paper presents the influence of processing temperature on some mechanical-physical properties of thermoplastic polyurethane (TPU), grade Desmopan KA 8377, used for injection moulding of performance sport products. The test pieces were moulded at the following real injection temperatures : 200°C, 210°C, 220°C, 230°C and 240°C. It was determined that the in-mould (cavity) pressure decreased with increasing of the processing temperature. Also TPU was thermally analyzed through: Thermogravimetry (TG), Differential Scanning Calorimetry (DSC) and Dynamic- Mechanical Analysis (DMA). It was established that 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.
