Development of Polyester / Polyethylene Post Consumer Scrap Alloy

ABSTRACT: – The increasing awareness of environment, government has promoted great interest in selected waste collection and has attracted the interest of research groups to challenge of converting recycled plastic into useful products. Converting PET containing film laminate waste is studied to obtain a new material with enhanced properties. In present study different percentage of film laminate used using Twin screw extruder and were subjected to the evaluation of materials efficiency. The success of the project depends mainly on the possibility of obtaining a compatibilized blend between two polymers. Ternary blends of PET/(PET/PE)Laminates/compatibilizer in weight composition of 29/71/0, 26/64/10, 68/21/10, 44/46/10 is prepared and studied to obtain post consumer scrap injection moldable thermoplastic materials. Before blending the basic material and compatibilizer is preblended at different ratios. This material is injection moldable and is suitable for the manufacturing of outdoor furniture, Garden pavers, Crate handles, Shipping pallets, Electrical products etc. This waste is available in huge quantities with film converting units in the form of trims and other rejects. At present, its disposal is a problem for industry. Differential Scanning Calorimetry, Thermogravimetric Analysis and a series of mechanical testsTensile strength, Flexural strength, and Impact strength are carried out according to ASTM D 638, ASTM D 790, and ASTM D 256 to investigate the phase behavior, the efficiency of compatibilization and the mechanical properties of the blends.
