Abstract :
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.
