In this project, binary blend PP/EPDM and tertiary blend PP/Egg shell powder/ Fish bone powder and binary blend PP/Egg shell powder and PP/ Fish bone powder has been prepared and studied. Effect of egg shell powder and fish bone powder content on mechanical performance of PP/ Egg shell powder/ Fish bone powder blend has been studied for binary blend and tertiary blend system by carrying out unnotched Izod impact and Tensile test Processingmethod hasto be employed are filler and EPDM hasto bemixed first and then melt blended with PP. Effect of addition egg shell powder and fish bone powder on mechanical performance oftertiary blend and binary blend has to be compared with tertiary blend of PP/EPDM/talc for varying composition Egg shell powder and fish bone powder with same composition of EPDM /. Thus polypropylene modified with EPDM and different fillers gives good balance between toughness and stiffness, thereby extending its end use application.
