Abstract: 
The aim of this study has been the utilization of recycled polyethylene for modification of physical and mechanical properties of particleboard. Therefore, three levels of resin content ( 10, 7 and 4% ) and three levels of recycled polyethylene (content 5, 10 and 15% in surface layer of mat) were used in particleboard production. . Also three boards with 10% resin content in surface layer and without polyethylene were produced as control samples. The physical and mechanical properties of boards were measured and analyzed. The results of this study indicated that with increasing the recycled polyethylene content, the MOR, MOE and thickness swelling of boards were improved significantly and the boards with 15% recycled polyethylene compared to control boards showed 59 and 53% improvement respectively. Also the results revealed that the water absorption of boards decreased with increasing the recycled polyethylene content, and the minimum water absorption was observed in the boards with 15% recycled polyethylene. Based on the results of this research and considering the increasing of polymeric residues in the environment, the utilization of recycled polyethylene in particleboard production provide multiple advantages.
