Heat Resistance Properties of an Cured ATPU/Epoxy Resin

Abstract:

Thermogravimetry (TG-DTA) method was used to study the heat resistance properties and the thermal decomposition kinetics of the aromatic amine-terminated polyurethane (ATPU)/Epoxy Resin System (E-44) which includes both flexible chains and rigid structural units. The results indicate that the decomposition temperature of the cured ATPU-2/E-44 is higher than that of the cured ATPU-1.5/E-44, and thermal decomposition residual of cured ATPU-2/E-44 is higher than that of cured ATPU-1.5/E-44 system. These results denote that the cured ATPU-2/E-44 has better heat resistance. The results of decomposition kinetics showed that the decomposition reaction activity of the ATPU-2/E-44 system is higher than that of ATPU-1.5/E-44.
