Effect of recycling process to the physical and mechanical properties of polypropylene / Ngadang Manggan
Polypropylene is a versatile material as it is used in variety application such as personal protective equipment (PPE), food packaging, automotive part and household. At the same time, there is a huge increment in plastic waste in the world and causing the seriousness of environmental pollution. For...

Polypropylene is a versatile material as it is used in variety application such as personal protective equipment (PPE), food packaging, automotive part and household. At the same time, there is a huge increment in plastic waste in the world and causing the seriousness of environmental pollution. For that reasons, industries have defined many ways to recycle plastic materials mainly to resolve the environment pollution. This study aims to investigate the maximum cycles can be sustained by the polypropylene as well as maintains its physical and mechanical performance. Previous findings showed the study up to 9th cycles of polypropylene. Hence, this study investigated the recycled polypropylene from 10 to 14 times using injection molding process. The injected products were tested by the tensile and flexural test. The specimens were also studied on their shrinkage and appearance.
