| ABSTRACT: In last few years with the increasing use of polymeric materials the disposal of the used material became a serious problem. As polyethylene is one of the common used polymers in many applications it represents a significant amount of the total municipal waste of thermoplastic materials. Thus recycling process of polyethylene is a subject which needs more investigation of the mechanical properties was carried out on virgin and recycled /virgin high density polyethylene (HDPE) to study the effect of three successive generations of HDPE as well as of the amount of recycled material added to the virgin one on the density, tensile, impact, and creep properties. The results showed that with recycling the HDPE three times, the density as well as the modulus of elasticity, the percentage elongation, the impact strength, and the recovery percentage of the HDPE decrease while the tensile strength increasing the recycled to virgin ratio of HDPE the density, the impact strength, and the recovery percentage increase while the modulus of elasticity, the percentage elongation, and the tensile strength remains almost constant. | ||
