Study on the influence of recycled material on the tensile strength of HDPE products

Abstract

Abstract The content of this paper concerns to the new tendency in industry, the concept of circular economy, based mainly on the decrease in plastic waste pollution by recovery and at source and on the significant optimization of production costs. The mechanical tests have been made on handles injected from several mixtures of grinded HDPE, with different melt flow rates and in different proportions, in order to establish the conformity of the final product to the imposed technical specifications regarding the breaking strength of this. For the industrial application, an important result is the validation of the recipes proposed for the preparation of raw material from recycled HDPE for which the final injected product preserves the physical-mechanical properties within the imposed limits. The study shows that in certain cases, for the preparation of the raw material, it could be used up to 100% recycled material, without affecting the technical specifications of mechanical resistance imposed on the final product.
