In this research the utilization of Acacia wood (Acacia salicina) in medium density fiber board production was investigated. Sample boards were made from Acacia fibers at two resin contents (10, 12%), two press temperatures (175, 185 ˚C) and three press times(3, 4, 5 min). The results were analyzed based on a complete randomized design (CRD) under a factorial experiment. Results revealed that increase of resin content had a positive effect on MOR and MOE and thickness swelling of MDF. At 12% resin content, MOR and MOE were respectively determined as 18.97 MPa and 1912 MPa. Also thickness swelling after soaking in water for 2 and 24 hours decreased from 15.87 and 20.96% to 10.76 and 16.49%, respectively. Internal bond strength (IB) was higher at 4 min. press time than 3 and 5 min. The IB of the boards, which were made at 4 min press time, was determined as 0.63 MPa. In general, the results showed the possibility of using Acacia wood in MDF production with proper physical and mechanical properties.
