In this research, the effect of wood species & particle size water absorption property of composite made of four species Fir, Beech, poplar and Alder sawdust and high density polyethylene were investigated. Wood plastic composite was made from dried Fir sawdust as filler at 70% ratio by weight and high density Polyethylene in batch process at 185 °C temperatures, at two particle sizes mesh 40 and mesh 80. MAPP was as coupling agent then were determined and compared their water absorption property according to ASTM D570 after 2 & 24 hour immersion at distilled water. Water absorption percent decreased in 3-12% range with increasing particle size. There were differences between different species water absorption property, but this difference did not significantly affect.
