Blending of LLDPE with SiO₂ via extrusion

Environmental pollution problems are becoming severe nowadays especially at the dumpsite. Thus it is imperative to develop new materials such as producing plastic that is ecological friendly to environment yet it has been found that there are limited research on the blending of LLDPE with inorganic material such as SiO2. This work is done to investigate the synthesis of LLDPE/SiO2 composite at different ratio and to investigate the characterization of composite by using FTIR and the mechanical properties of tensile and elongation at break. The composite is produced through extrusion process by using twin-screw extruder and being analyzed by using FTIR, TGA and the universal tester machine. The result demonstrated that the composite with lowest SiO2 filler content which is 4% has the best mechanical properties. The production of this composite will be useful to the industry as the mechanical properties of the composites has been enhanced hence producing a better plastic materials.
