Morphology and Mechanical Properties of HDPE/Bio-Polymer as Compounding Materials
The effect of bio-polymer as compounding material in mechanical properties of HDPE is described in this study. 10% of bio-polymer was added to the HDPE and then mixed by using Brabender Plastograph machine using mixer and roller screw and then test specimens were prepared by injection moulding. The origin bio-polymer (VOP), HDPE and the compounding bio-polymer/ HDPE (CDM) were compared by using tensile test and the microstructure was investigated through scanning electron microscopy (SEM) for the fractured surface of the samples. The tensile strength of CDM was found to increase that is 17.47 MPa compared to pure VOP that only 5.69 MPa while pure HDPE has the highest tensile strength that is 20.98 MPa. By adding 10% bio-polymer to the HDPE was increased up the strength at about 207.16% while pure HDPE produced 268.91% increment with VOP as the precursor. SEM of the VOP produced brittle fracture surface while CDM have brittle and ductile surface and HDPE has totally ductile surface with highest plastic deformation properties of all.
