Abstract
The thermal degradation of cable ties of polyamide (PA6,6) neat and UV stabilized was investigated by thermogravimetry (TG) and its derivative (DTG) at several heating rates between 5 and 80 oC min-1 in helium atmosphere. High heating rates signal novel peaks in the DTG curves that indicate melting temperature of PA6,6. The kinetic parameters calculated via isoconversion and nonisothermal data using the Flynn-Wall-Ozawa, Kissinger and Coats-Redfern methods showed comparable activation energy values. Exposure of the ties to outdoor environment causes pre- mature stress cracking and brittle failure due to prevalence of crosslinking reaction occurring in the polymer chains.
