Particleboards with densities of 0.60-0.70 g/cm3 were manufactured from Paper mulberry (Brosonatia papyrifera) wood having specific gravity of 0.50. Boards were bonded with urea-formaldehyde resin glue. Mechanical properties (MOE, MOR, IB strength and screw-withdrawal resistance) and dimensional stabilities (Thickness swelling, water absorption and Linear expansion) of the boards were determined. Mechanical properties of boards of paper mulberry increased with board density. The boards with density 0.66 g/cm3 have better dimensional stability than those with the density lesser or greater than this value.
