| Summary: | In this study it was investigated the incorporation of sago
starch in low-density polyethylene matrix (LDPE) to
enhanced mechanical properties and to obtain partially
biodegradable product with the aim to reduce the plastics
wastes in the environment. The compounding of the LDPE
with sago starch was prepared via a twin screw extruder followed by injection molding. Studies on their physical,
mechanical properties and thermal properties of each
formulation before and after natural weathering exposure
were carried out by tensile, thermogravimetry analyzer
(TGA-DTA) and scanning electron microscope (SEM). The
biodegradability of sago starch–filled LDPE blend was
studied by monitoring its weight loss. Tensile tests, TGA
and SEM imaging were also carried out on the samples
before and after degradation. Imaging showed that the
increase in starch content from 5% to 20% in the
formulations increases the biodegradability of the
samples. |
