Abstract
This paper presents the influence of the processing temperatures on the physico - mechanical properties of polyamides (PA) used in injection molding of high performance sport products. The samples were obtained by processing PA at the following temperatures: 270, 285, 300, 315, 330 and 345°C. It was established that the pressure in the mold decrease as the processing temperature rise. Further, thermal analyses were performed (TG, DSC, and DMA) and it was noticed that the processing temperature had an influence on the thermal stability of the polymer, but the glass transition temperatures (Tv) and melt temperatures (Tt) were poorly influenced by the processing temperature. Keywords: polyamide, injection molding, TG, DSC, DMA
