Effect of Higher Thermoplastic Starch Content on TPS/LDPE Plastics

Article Preview

Abstract:

The TPS/LDPE starch plastic was prepared in the presence of the compatibilizer after the preparation of thermoplastic starch (TPS). The effect of starch content to properties of TPS/LDPE was studied by DSC, TG, electronic tensile machine and SEM. The results showed that the system had a good compatibility between TPS and LDPE, and the thermal properties were improved because of the forming of chemical bonds. When the TPS content is more than 58.54%, the tensile strength and elongation at break decreased dramatically, the main reason is the transformation of the continuous phase and the dispersed phase.
