Abstract

Recycled plastic wastes polyethylene terephthalate (PET), high-density polyethylene (HDPE) and polypropylene (PP) were studied in the presence of Ethylene glycidyl methacrylate (EGMA) copolymer compatibilizer, as raw materials for producing automobile bumper. These plastic wastes were cleaned and dried, then crushed to < 3 mm in size and further dried for 4 h to remove moisture. Crushed samples were weighed in different proportions with varying amount of compatibilizer (5–15 g) and manually mixed. Recycled composite plastic of 150 × 150 × 3 mm in length, width and thickness, respectively, was produced from weighed samples in an injection moulding machine at 150–220o C and pressure of 150 bar. Mechanical tests and morphological observation were carried out on the blend. The mechanical properties were more dependent on EGMA in the blend
