Effect Effects of mechanical properties on blend loading ratio for recycled High Impact Polystyrene and Acrylonytrile-Butadiene-Styrene
In this work, the blend loading ratio of recycled HIPS/ABS will be conducted using twin screw extrusion machine. It is used extensively for mixing compounding, or reacting polymeric materials. The flexibility of twin screw extrusion equipment allows this operation to be designed specifically for the formulation being processed. The polymer blend will be injected using injection moulding machine according to ASTM D638. To investigate the mechanical properties; RSM approach will be used to setup the experimental work according to the machine parameter and levels used. A binary blend (45%ABS–50%HIPS wt) was conducted on a conventional injection moulding machine, at 190 – 195 – 200 – 210 °C melting temperature respectively. Finally, ternary blends were prepared by varying the SEBS content, from 0% to 30 % (wt %), at the same conditions of ABS-HIPS blends. It was found that the tensile strength (125.44 MPa) for recyled HIPS/ABS is maximum when the value of melting temperature (200˚C) and injection pressure (90 MPa) for the value of the injection moulding parameters setting.
