The effects of filler loading and coupling agents on properties of recycled high density Polyethylene/wood fiber composites

The recycled high density polyethylene (rHDPE)/wood fiber (WF) composites had been prepared using Brabender Plasticorder at temperature 160˚C with rotor speed of 50 rpm. The effect of wood fiber loading and coupling agents on tensile properties, water absorption, morphology, spectroscopy infrared...
