AB  - The aim of this study was to investigate the feasibility of using nonmetallic 
      printed circuit board (PCB) waste as filler in recycled HDPE (rHDPE) in 
      production of rHDPE/PCB composites. Maleic anhydride modified linear low-density 
      polyethylene (MAPE) was used as compatibilizer. In particular, the effects of 
      nonmetallic PCB and MAPE on mechanical properties of the composites were assessed 
      through tensile, flexural and impact testing. Scanning electron microscope (SEM) 
      was used to study the dispersion of nonmetallic PCB and MAPE in the matrix. 
      Nonmetallic PCB was blended with rHDPE from 0-30 wt% and prepared by 
      counter-rotating twin screw extruder followed by molding into test samples via 
      hot press for analysis. A good balance between stiffness, strength and toughness 
      was achieved for the system containing 30 wt% PCB. Thus, this system was chosen 
      in order to investigate the effect of the compatibilizer on the mechanical 
      properties of the composites. The results indicate that MAPE as a compatiblizer 
      can effectively promote the interfacial adhesion between nonmetallic PCB and 
      rHDPE. The addition of 6 phr MAPE increased the flexural strength, tensile 
      strength and impact strength by 71%, 98% and 44% respectively compared to the 
      uncompatibilized composites.
