Abstract
Thermal properties of the elastic filament DOW XLATMwere analyzed by differential scanning calorimetry (DSC) and thermogravimetry analysis (TG). Besides, the elastic recovery characteristics after heat treatment were also discussed. The DSC scan shows typical endotherms and its melting temperature (Tm) ranges from 28 °C- 65 °C. TG analysis indicates that the thermal degradation begins at 285 °C and the highest weight loss rate occurs at 461.9 oC. When the filaments are heat treated under relaxation or at constant elongatiSuperscript texton, their elastic recovery ratios all decrease with the increase of the heat treatment temperature except for 50 °C.
