ABSTRACT In recent years there is a growing concern over increasing consumption of PVC made products, as the items entering the waste stream from these materials are increasing drastically. Recycling of plastic products is one of the most important actions currently available to reduce the impacts and delineate one of the most dynamic areas in today’s plastic industry. However, Mechanical properties of products made from recycled plastics get affected which is a major drawback that limits their use. In this study, we adopted the L9 Taguchi Orthogonal Array method to improve the mechanical properties of products made from different compositions of recycled with virgin PVC produced by the extrusion process. The experimental design was carried out with four process parameters (i.e., barrel temperature, die temperature, extruder speed, and extruder pressure) which are controllable each at three levels is tested for the optimal combination of factors and levels in the extrusion process. The effects of processing parameters and the blending of recycled PVC in different compositions on the mechanical properties are investigated. The results revealed that the product made of 20% recycled PVC and 80% virgin PVC exhibits similar flexural modulus on par compared with products made with virgin PVC. The mechanical properties of products made from recycled with virgin PVC compositions can be improved by optimizing the process parameters during the extrusion process. Keywords: Extrusion, Virgin PVC. Recycled PVC.
